WHEN YOUR EFFORTS ARE NOT RESULTING IN PROGRESS.
You Do Not Need Another Lecturer. You Need Someone Who Notices.
Any class can explain concepts, but improvement begins when the right mentor observes you, notices where your thinking breaks down, and understands why your mistakes keep returning and addresses what must change.
01
Repeating the Same Mistakes
You understand the concept, but ignore the mistakes. A mistake you ignore today becomes the mark you lose tomorrow.
If Left Uncorrected!
It can spread across similar questions, reduce accuracy and continue costing marks even after you have studied the concept several times.
HOW A MENTOR CAN HELP
A mentor traces the mistake to the exact calculation, interpretation or decision where your thinking breaks down. Through an error log, targeted practice and repeated checks, the faulty process is corrected—not merely the final answer.
02
Mocks not improving scores
You are taking many mocks, but more and more mocks cannot fix wrong test strategies.
If Left Uncorrected!
Mocks without diagnosis reinforce poor question selection, wasting time, and avoidable errors. Further, time, confidence and valuable prep time is lost.
HOW A MENTOR CAN HELP
A mentor analyses how you attempted the test—not only the final score. Question selection, time usage, accuracy, hesitation and missed opportunities are reviewed, followed by a specific correction plan and measurable targets for the next mock.
03
Every Area Seems a Weak Area
Your unresolved doubts are quietly becoming your weak areas. Every unattended problem area results in bigger weaknesses.
If Left Uncorrected!
A doubt may seem small today. But, as connected concepts accumulate, avoidance increases, confidence falls and more questions begin to feel unfamiliar or unsafe to attempt.
HOW A MENTOR CAN HELP
A mentor identifies the root of the confusion, resolves the immediate doubt and checks whether related concepts have also been affected. Focused follow-up questions ensure that the topic becomes usable instead of remaining an avoided weakness.
04
Until the Clock Starts Ticking
You know how to solve it ...until it is in a test. The ticking clock exposes what untimed practice is hiding.
If Left Uncorrected!
Under time pressure, you may spend too long on the wrong question, abandon easier marks and finish the test knowing that your actual ability never appeared in your score.
HOW A MENTOR CAN HELP
A mentor trains you to recognise question difficulty, choose attempts intelligently, set time limits and leave unproductive questions without panic. Timed drills, test simulations and post-test analyses turn knowledge into dependable examination decisions.
05
Studying Daily, But No Results
Your working hard every day does not automatically mean that you are actually getting better.
If Left Uncorrected!
Hours of study can create false confidence while weak topics, incomplete revision and repeated errors remain hidden. By the tests reveal the gaps, months of efforts may already have been used inefficiently.
HOW A MENTOR CAN HELP
A mentor converts activity into measurable progress through clear weekly priorities, targeted practice, revision checkpoints and regular accountability. What you studied, what improved and what still needs attention remain visible throughout your preparation.
06
You Know But Cannot Express
You know the answer, but you cannot express it when it matters. A strong answer has no value if you cannot communicate it.
If Left Uncorrected!
When your ideas appear unstructured, hesitant or unclear, interviewers and evaluators cannot see the quality of your knowledge. A strong academic profile may not make up for the loss.
HOW A MENTOR CAN HELP
A mentor helps you organise your thoughts, build clear response structures and communicate with composure. Mock interviews, speaking practice, writing exercises and specific feedback improve both what you say and how convincingly you say it.
The real difference is not how much content you receive.
It is whether an experienced mentor helps you use it to rectify mistakes before they cost marks, confidence and valuable time.

Dipanjan Bhowmik
LESS A LECTURER. MORE A SENIOR YOU CAN TRUST
Turning Maths Anxiety
Into Confidence
Dipanjan is not another teacher who solves difficult questions quickly and moves on. He is someone who listens, identifies where you are stuck, and explains without making you feel that you should already know the answer.
That is why Dipanjan feels less like a conventional faculty member and more like the dependable college senior you turn to before an examination. He understands unfinished syllabi, repeated calculation errors and the hesitation behind asking a “basic” doubt.
Ask freely, break difficult questions into smaller decisions and understand why a method works before trying to make it faster. Dipanjan helps you recognise where a method may fail, correct the reasoning behind mistakes and apply the same logic independently. You gain more than solutions: reassurance after a poor mock, direction when preparation feels scattered and a clear next step.

What Changes When You Learn With Dipanjan
01
You Ask the Question You Were Hesitating to Ask
Dipanjan listens without judgement, identifies the actual confusion and explains from the point where you genuinely need help.
02
You Break Difficult Questions Into Smaller Decisions
Dipanjan teaches by separating the data given, identifying what the question requires, and converting an intimidating problem into manageable steps.
03
You Choose Methods Instead of Memorising Them
Dipanjan helps you to learn selecting an approach according to the question, the examination and your current level of accuracy.
04
You Turn Every Mistake Into a Precise Correction Step
Dipanjan examines where your error began and corrects the reasoning behind the mistake so that it does not return in the next test.
05
You Convert a Poor Mock Into Your Next Action Plan
Dipanjan identifies what went wrong in a mock, decides what needs immediate practice, and tests the required changes in your next mock instead of merely taking another test.
06
You Build Speed and Accuracy After You Build Clarity
Once your reasoning becomes stable, Dipanjan focuses on where steps can be reduced, calculations simplified and decisions taken faster without sacrificing accuracy.

Talk to Dipanjan about cricket, music, thriller movies, food or his love of travelling to the hills, and the conversation moves into hours. These interests reveal the relaxed, curious and approachable person behind the mentor. Whether he is discussing a tense cricket finish, a memorable soundtrack, a gripping thriller, a favourite meal or the calm of a mountain journey, he connects with students without forcing formality. That ease makes it simpler for you to ask questions, admit confusion and speak honestly about poor mocks or unfinished preparation.
With Dipanjan, mentoring feels personal, practical and reassuring—not like a classroom transaction.
Learn from an experienced mentor who combines professional guidance with the accessibility and reassurance of a trusted college senior.
Shubhadeep Roy
LESS A TRAINER. MORE A STRATEGY BUILDER.
Turning Complex Data Sets
Into Clear Decisions
Shubhadeep doesn’t merely solve a difficult set and show you the answer. He is someone who helps you see what the data means, which possibilities matter, and what decision making the question demands.
Shubhadeep brings the analytical discipline of IIT Kharagpur and IIM Calcutta together with years of experience in reasoning, communication and interview preparation. He helps you organise scattered information, recognise patterns, eliminate unproductive paths and choose attempts with greater control.
In his class, the objective is not to make every set look easy. It is to make your thinking more deliberate, adaptable and dependable. Whether you are facing an unfamiliar DILR set, planning a mock-test strategy or structuring an interview response, Shubhadeep helps you remove the confusion, examine the evidence and arrive at a clear, defensible decision.
Talk to Shubhadeep When
What Changes When You Learn With Shubhadeep
01
You Understand Every Set Before Attempting It
Shubhadeep helps you identify the structure, constraints and hidden relationships before you invest time in calculations or commit to an approach.
02
You Choose Questions With Greater Strategic Control
Shubhadeep trains you to judge difficulty, opportunity and risk so that your selections protect both time and accuracy during the test.
03
You Replace Random Trials With Structured Reasoning
Shubhadeep shows you how to organise information, test possibilities systematically and eliminate options without allowing the set to control your thinking.
04
You Convert Mock Performance Into Better Decisions
Shubhadeep analyses your selection, sequencing, hesitation and abandonment patterns, then turn those observations into specific changes for your next mock.
05
You Prepare for Questions That Test Your Composure
Shubhadeep draws on my experience of facing interviews across the top IIMs to prepare you for unexpected, layered and uncomfortable questions.
06
You Learn to Defend Every Interview Answer
Shubhadeep helps you anticipate follow-up questions, test the logic behind your claims and present answers that remain credible under sustained scrutiny.

The Person Behind the Mentor
Beyond the Classroom
Talk to Shubhadeep about theatre, cinema, photography, cats, or backpacking, and you discover how naturally he connects analysis with observation. His book, The Country Within, grew from a 45,000-kilometre journey documenting 13 Indian festivals through photographs and essays. That experience reflects the curiosity he brings into mentoring: look closely, question first impressions and understand the larger pattern before reaching a conclusion.
His association with theatre and cinema also shapes the way he thinks about expression, perspective and audience. These interests make conversations with him thoughtful without becoming formal. You can discuss a difficult DILR set, an uncertain interview response or an unfamiliar idea with the same openness—and leave with a clearer way of seeing it.
Learn with a mentor who turns analytical depth, creative perspective and practical strategy into calmer decisions and more convincing performance.
Prajnan Ray
LESS A TEACHER. MORE A PERSPECTIVE-BUILDER.
Turning Your Thoughts
Into Impact
Prajnan is not another teacher who corrects grammar, explains vocabulary, solves data-sets and stops there. He is someone who helps you understand ideas, question assumptions and express what you think with clarity and conviction.
Prajnan combines 15+ years of aptitude and communication training with an MBA from MDI Gurgaon, a technology background and experience in programme design and interview preparation. He helps you read beyond the words, recognise the argument, connect current affairs with wider issues and build responses that sound informed rather than memorised.
In class, the goal is not polished English or solving questions for its own sake. It is sharper comprehension, stronger reasoning and communication that holds up under pressure. Whether you are solving a question, participating in a group discussion or facing an interview panel, Prajnan helps you turn scattered thoughts into structured, relevant and persuasive expression.
Talk to Prajnan When
What Changes When You Learn With Prajnan
01
You Read Beyond Words and See Arguments
Prajnan teaches you to identify purpose, tone, assumptions and structure so that comprehension becomes analytical rather than surface-level reading.
02
You Express Complex Ideas With Ease
Prajnan helps you organise scattered thoughts into logical responses that are precise, relevant and easy for an examiner or interviewer to follow.
03
You Build Opinions That Can Withstand Questions
Prajnan pushes you to examine evidence, challenge convenient assumptions and support every position with reasoning instead of borrowed or rehearsed statements.
04
You Connect Current Affairs With Larger Contexts
Prajnan shows you how to connect events with history, economics, society and policy, making your discussions and interview answers substantially stronger.
05
You Convert Verbal Errors Into Lasting Improvement
Prajnan diagnoses why an answer failed, identifies the thinking error behind it and gives you a method you can reuse independently.
06
You Communicate Calmly When the Pressure Rises
Prajnan prepares you to listen, think and respond under pressure without becoming vague, defensive, overcomplicated or dependent on memorised answers.

The Person Behind the Mentor
Beyond the Classroom
Talk to Prajnan about books, world cinema, digital marketing, website building or travelling to the hills, and the conversation rarely stays on the surface. Reading gives him new arguments and perspectives; cinema sharpens his interest in character, culture and the many ways a story can be interpreted, while travelling adds places, people and liveliness to those ideas. He is also interested in philately, which reflects the patience to notice how history can sit inside something very small.
These interests naturally enter his mentoring. A classroom discussion may begin with a passage and move towards politics, society, language or human behaviour. That wider curiosity helps students become better readers, more informed speakers and more thoughtful interviewees—without making every conversation feel like another formal lesson.
Learn with a mentor who helps you read more critically, think more independently and express every idea with clarity, relevance and confidence.
Indranil Roy
LESS A TUTOR. MORE A PROBLEM SOLVER.
Connecting Aptitude With
Professional Readiness
Indranil brings together aptitude training, interview preparation and first-hand corporate exposure to help students perform with greater structure when selection pressure rises. An alumnus of XIM Bhubaneswar with experience at Havells India, he understands that solving a question is only one part of being selection-ready. Students must also explain their reasoning, organise their thoughts, participate meaningfully in group exercises and respond calmly during interviews.
Across more than six years of teaching and 1,000+ classes, Indranil has worked with students in Quantitative Aptitude, Data Interpretation and Logical Reasoning while also conducting mock interviews, group discussions and group exercises. His mentoring connects classroom methods with professional expectations, helping students become more methodical in problem-solving and more aware of how their performance is evaluated.

02
You Learn to Explain Every Important Decision Effectively
He asks students to justify choices, expose assumptions and communicate the reasoning behind an answer with greater precision and confidence.
03
Your Aptitude Learning Connects With Professional Expectations
Drawing on corporate experience, Indranil shows how structured thinking, prioritisation and judgement remain valuable well beyond entrance examinations.
04
Interviews Become Conversations, Not Interrogations
Indranil prepares students to understand questions, organise relevant evidence and answer calmly instead of rushing into impressive-sounding but unsupported responses.
05
Group Exercises Become Purposeful Rather Than Performative
Indranil helps students contribute with relevance, listen actively, build upon others’ ideas and demonstrate leadership without dominating the discussion.
06
Your Preparation Begins Reflecting Real Performance Expectations
Indranil’s mentoring connects accuracy, communication, composure and awareness, helping students understand what evaluators actually notice during selection processes.

The Person Behind the Mentor
Beyond the Classroom
Indranil enjoys painting, football and travelling—interests that combine observation, energy and a willingness to explore unfamiliar perspectives. His reading moves across history, Indian epics, thrillers, fantasy and biographies, giving him a wide range of stories, personalities and situations to draw upon.
These interests make conversations with him extend naturally beyond formulae and interview frameworks. A discussion may move from a footballing decision to a historical turning point or a character’s judgement in a thriller. That variety helps students engage with him more openly while developing curiosity, perspective and the ability to connect ideas across academic, professional and everyday contexts.
Learn with a mentor who takes you beyond correct answers—helping you think clearly, explain convincingly and perform when selection decisions matter most.
Indraneel Biswas
LESS AN INSTRUCTOR. MORE A ZEN MASTER.
Turning Decades of Experience
Into Steady Progress

04
You Learn When Accuracy Matters More Than Speed
Indraneel teaches students to protect sound reasoning first and pursue faster methods only after the underlying approach becomes reliable.
05
Feedback Becomes Honest, Personal and Consistently Useful

Beyond the Classroom
Indraneel values the relationships and experiences that keep life grounded. He enjoys connecting with friends, travelling, reading and exploring food and cuisine. These interests reflect the same qualities visible in his mentoring: curiosity, openness and genuine attention to people. Travel exposes him to different settings and perspectives, while reading allows him to continue learning beyond familiar academic boundaries. His interest in food and conversation also gives him an easy, approachable presence outside formal classroom interactions.
Students often benefit from mentors who can discuss more than tests and scores, and Indraneel’s varied interests help him build comfortable, lasting connections without losing the discipline and purpose that define his guidance.
Learn with a mentor who gives you seasoned guidance and keeps your preparation disciplined, realistic and personally directed.
How PREPON Faculty Work Differently
Mentoring That Stays Involved. Your Preparation Is Observed, Corrected & Strengthened.
At PREPON, faculty involvement does not end after a concept has been taught. Mentors observe how you approach questions, identify recurring errors, resolve doubts, review practice and help you improve your performance over time. Small batches, one-to-one interaction and technology-enabled classrooms allow faculty members to notice what generic teaching systems often miss. You receive guidance that remains connected to your preparation—from understanding a concept to applying it accurately under test and interview pressure.
