Today’s focus
✦ Chosen because it unlocks Newton’s laws, work & rotational motion.
How it works
Two things. That’s it.
You don’t plan, sequence or pick difficulty. You open the app and you make the wheel green.
Your next move is already chosen
The engine ranks every concept by mastery, stability and forgetting risk — then surfaces the single move that lifts your score most. No menus, no decisions.
Ranked by projected impact
✦ Top pick — starts today’s sessionMake the wheel green
Every concept is a slice. Green means truly mastered — not just attempted. Your job is simple and visible: close the gaps until there are no blind spots left.

Practice
One concept at a time, until it’s done
Every question here has been asked in a real JEE Main paper. You get one concept at a time, and you stay on it until you can do every kind of question the exam asks on it — not just the one you got right.
- Real past-paper questions, grouped by concept
- Stuck? The solution is explained step by step, not dumped on you
- We warn you about the mistakes students usually make on that concept
A ball is thrown at 20 m/s, 30° above the horizontal. What is its speed at the highest point?
Speed
You know it. Can you do it in time?
When you practise, you have all the time you want. In the exam you don’t. A timed set gives you 5 problems from one question type you can already solve, and measures you against the time a real paper allows — so you stop losing marks on questions you actually knew.
- Each question has its own target time, based on how hard it is
- You see your time next to the exam’s time, side by side
- The clock runs, but it never stops you in the middle of a question
- We start you on the types where being slow costs you the most marks
Spin-only magnetic moment calculation
You have worked through these. We have never had you against a clock on them.
Mastery does not move — this is about the clock, not whether you can do it.
Remember
Don’t let the backlog build up
Concepts you’ve already done come back to you a few at a time, spread across your daily practice, so revision never turns into a backlog you have to catch up on. You can still open any chapter and revise it yourself whenever you want.
- Concept revision — each concept returns before you forget it
- Chemistry recall cards, a few every day
- Every formula for the chapter, one tap from your focus card
Tests
Exam conditions, so the score means something
Real format, real timing. Start with the chapter you just finished and work up to a full paper.
- Chapter tests — one chapter at a time, when you’ve just finished it
- High-yield tests — the topics the exam asks most
- Full mock papers — all three subjects, real format and timing
- Custom tests — pick your own subjects, chapters and time
Curated tests
— built from real exam analysis, same for everyone.

When you keep getting it wrong
This is not where you learn a chapter for the first time — your class and your books are. But when the same concept keeps going wrong, Rhovecs takes you through it in five steps, and the short chapter notes show you which parts you are weak in.
How it decides
AI explains things to you. It never decides what you practise.
- Rhovecs keeps a score for every concept, built only from questions you actually answered
- What to revise next comes from your results, not from AI
- Same data, same plan, every time — and you can check the reason for any choice
Why it’s different
Not a tutor. Not a question bank. A deterministic coach.
We decide what’s worth your next 20 minutes — and tell you why. Explainable, every score auditable. Not a black box.
Catches illusory mastery
A right answer for the wrong reason doesn’t count. We test whether you actually own the concept.
Prerequisites enforced
You don’t get pushed into a topic you’re not ready for. Foundations come first, in order.
Knows which technique you failed
Not just “wrong” — the exact method that broke down, isolated and named.
Classifies why you got it wrong
Concept gap, careless slip or technique error — each is treated differently, because the fix is different.
Tracks when you’ll forget
A forgetting-risk model schedules each concept’s return before it decays out of memory.
Instant same-technique drill
Miss a method and you can drill structural variants of it on the spot, until it holds.

Questions, answered
Honest answers, no spin.
No. A question bank hands you problems and leaves the thinking — what to study, in what order, at what difficulty — to you. Rhovecs makes those decisions for you each session, based on your real mastery and forgetting risk. The problems are a means; the system’s judgement about which problem is the product.
A tutor is a person with limited hours and memory. Rhovecs is a system: it watches every answer, never forgets a weak spot, and decides your next move the same calm way every day. It isn’t a personality and it won’t motivate or shame you — it tells you what’s worth your next 20 minutes, and why.
Rhovecs was built by a parent for their own child’s JEE prep, then opened up. We’re early and honest about it: no inflated numbers, no fake reviews. Trust is earned by the system being explainable — every recommendation and score is auditable, so you can always see why it decided what it did.
Yes. After the 14-day full-access trial, free gives you today’s focus, a daily set of 15 problems, spaced review and the formula library — the core loop, for as long as you want it. Pro removes the daily cap and adds the weekly parent report and the full coach.
Either. Many students use Rhovecs alongside coaching — it turns “what should I practise tonight?” into a single answer and keeps revision on schedule. If you’re self-studying, it can be your primary structure. It doesn’t fight your existing plan; it sequences your practice within it.
The full JEE Main syllabus — Math, Physics and Chemistry across Class 11 and 12. You mark what you’ve covered and the engine works within that, surfacing prerequisites before it moves you forward.
Once a week, Pro sends a short, plain-language summary: what was practised, where mastery moved, what’s on schedule next. No vanity metrics and no streaks — just an honest read on whether prep is on track, written for a parent, not a dashboard.
Especially then. Being behind usually means missing foundations, and that’s exactly what the engine enforces — it won’t skip you ahead into topics you’re not ready for. Starting early simply means more time for the forgetting-risk model to do its quiet work.
