The ClassPe Method
The structure that ensures success in the IAT exam.
Not a philosophy. A structure - five methods you can time, count and check.
In one answer
Most institutes describe their teaching. We can show you ours. The ClassPe method is five mechanics - a test calendar, a class where you practise instead of watch, an app that keeps you consistent, feedback after every test, and mentors who cleared the IISER Aptitude Test themselves. Every one of them is countable and checkable.
Method 1 · The Retention Curve™
Watch forgetting lose, three times.
Grey is what forgetting does to a taught concept. Blue is the same concept on the re-test calendar - the one idea every other method serves.
The Retention Curve™ · what you still recall
Illustrative recall - every re-test restarts the forgetting curve, and each restart decays slower, so the concept holds till exam day.
- 1
You learn it
Day 0 - the concept lands in a live online class, two classes a week per subject, recording up the same evening.
- 2
You start forgetting
Ebbinghaus, 1885: memory decays fastest in the first days. Every classroom on earth has this curve.
- 3
We re-test - three times
At 2 weeks, 1 month and 3 months, the concept is re-tested and re-lifted. On a calendar, not a whim.
- 4
You see the trend
Every re-test returns a score, a trend and a next step, the same evening.
Weekly test
every 14 days
Reinforces every concept from the last 14 days. Conceptual clarity, quick feedback while it's fresh.
Monthly test
every 30 days
Full syllabus completed till date. Balances revision with new learning.
Quarterly test
every 90 days
The entire syllabus of the last three months. Long-term retention, progress across cycles.
Three tests. Three re-lifts. One concept that's still there on exam day.
Method 2 · The class SOP
You don't watch the class. You work in it.
One class, on a clock: 3 hours 30 minutes - and almost half of it is you solving, not us talking.
Most coaching is a lecture you watch and homework you never do. That's spoon-feeding, and it collapses the moment the teacher leaves the screen.
At ClassPe, practice is not sent home - it happens in class, in front of the teacher who taught the chapter. Every class opens with the previous class's homework solved live, and closes with tomorrow's homework started live. You leave the class having already done the work, with your mistakes caught while they're still fixable.
Two classes per subject, every week - and every single one runs this exact clock.
Method 3 · The app
Consistency, engineered into your phone.
Preparation fails on the days nobody's watching. The ClassPe app is built for exactly those days.
A year of IAT preparation isn't won in class - it's won on the ordinary Tuesday when nobody is checking on you. So the app puts everything in one place: today's learn path, live classes, same-evening recordings, the Dynamic Sheet, your test calendar and your score history. You don't have to remember what to do next. The app already knows.
Good evening, Riya

Method 4 · The loop
You don't get adjectives. You get a report.
Every test returns a score, a trend, and a next step - the same evening, from a named teacher.
A test that only gives you a number teaches you nothing. A test that tells you why changes the next month.
After every test - weekly, monthly and quarterly - you get a detailed performance breakdown: what you scored, how it compares to your last attempt on the same concept, exactly which topics are weak, and what to do about it. Your weak spots don't just get flagged; they get added to that week's Dynamic Sheet, so the fix is scheduled, not suggested.
The same report lands on your parent's phone the same evening. Nobody is guessing how the year is going.

Five methods. One structure. One rank.
Old science, applied on a calendar. The lineage runs from Ebbinghaus (1885) to the modern spaced-retrieval literature - we just put it on a timetable and refused to break it.
The ClassPe Method
Students ask these questions.
How ClassPe teaches, tests and mentors for the IISER Aptitude Test (IAT) 2027 - answered plainly.
The IAT rewards students who remember and apply four subjects - Physics, Chemistry, Mathematics and Biology - under a 3-hour clock with negative marking. That needs three things: full NCERT Class 11 and 12 coverage, spaced revision so nothing decays before exam day, and repeated testing on the real pattern. The ClassPe method is built around exactly those three, on a fixed calendar.
This is the single biggest reason strong students under-score. Research on the forgetting curve (Ebbinghaus, 1885) shows memory decays fastest in the first days after learning. ClassPe's Retention Curve™ answers it by re-testing every concept three times - at 2 weeks, 1 month and 3 months - so a chapter you learn in August is still exam-ready in June.
Yes - it's one of the most consistently supported findings in learning science, from Ebbinghaus in 1885 through to the modern spaced-retrieval literature. The IAT is a long-horizon exam covering two years of NCERT PCMB, so retention matters more here than in a short-syllabus test. We didn't invent the science; we just put it on a timetable and refused to break it.
Two live classes per subject every week - eight classes in all, across Physics, Chemistry, Mathematics and Biology. Every class runs a fixed 3-hour-30-minute SOP, which works out to 28 live hours a week. Every class is recorded and up the same evening.
Every class follows the same clock: 30 minutes solving the previous class's homework live, 90 minutes of new concept, a 15-minute break, 60 minutes of worked examples and extension, and 15 minutes starting tomorrow's homework live. You practise inside the class, in front of the teacher who taught the chapter - no spoon-feeding, no homework you never open.
Every batch is exactly 50 students with five educators - four dedicated subject teachers (P·C·M·B) and one mentor who owns the batch. That's one educator for every ten students. The IAT is a four-subject exam, so you need a specialist in each, and a small enough room that your weak spots get noticed. We cap at 10 batches - 500 students a cycle, never more.
Testing runs on three tiers: a weekly test every 14 days on recent concepts, a monthly test every 30 days on the full syllabus to date, and a quarterly test every 90 days covering the last three months. Every test returns a detailed breakdown - your score, your trend against previous attempts on the same concept, your weak areas, and your next step - the same evening. Weak spots are added straight into that week's Dynamic Sheet.
Yes. Every re-test report lands on your parent's phone the same evening through The Loop - score, trend, next step, from a named teacher. Nobody has to guess how the year is going.
Doubts are answered the same day, on Telegram, by the teacher who actually taught that chapter - not a general helpline and not a stranger. In a 10:1 batch, the person answering already knows your test history.
The mechanics are identical for both the Doppler Batch (droppers) and the Kepler Batch (Class 12) - same 50:5 batch, same 3½-hour class SOP, same Retention Curve™ test calendar, same feedback loop. What changes is pace and load: Doppler is IAT-only and runs deeper, while Kepler is sequenced around your board exams.
