Study
The practice hub — six tool cards: guided Learn, adaptive Practice, full-length Exam Prep, spaced Revision (premium), a Mistakes notebook and the Skills Map.
What this screen shows
The Study hub gathers every way to practise into one card grid — guided Learn sessions, targeted adaptive practice, full mock tests, spaced revision, the mistake notebook and the skills map. Each card opens a focused tool. It is the core of Rank Booster: choose how you want to learn and go.
Common tasks
Open Learn to read a short concept card and then answer a couple of adaptive questions on it — repeating, read-then-recall.
Open Practice for adaptive questions tuned to your level — pick your board, class, subjects and chapters, choose a length, start.
Run Exam Prep for a full-length timed mock — minor test, chapter test, subject mock or full mock.
Use Revision to space out what you’ve learnt (premium).
Open Mistakes and start its Wrong Answers drill to redo only the questions you got wrong.
Open the Skills Map to see every topic and its SmartScore.
Tool cards in this hub
Seneca-style read-then-recall sessions. Pick your subjects, chapters and topics in the same scope picker as Practice (with the same Filters disclosure), then a fused session interleaves a short Smart Notes concept card with a couple of adaptive questions on what you just read, repeating and adapting as you go. Concept cards need the Smart Notes unlock for the subject; without it the session falls back to questions only. Routes to /rank-booster/learn.
Adaptive questions tuned to your level. Step 1 is the scope picker — board, class, subjects, then the chapters you want. Expand any chapter with its chevron to tick individual topics (topics with no questions are hidden), and use Add another scope to practise across two syllabi at once, such as your board chapters plus JEE Main. Under it sit a Filters disclosure (Type, Difficulty, Marks, Bloom's, Nature, Skill, Source, plus Previous-year and Competency flags), a live "questions available" count (which excludes questions you've already answered correctly) and length templates, then the session starts. In the session you can tap options, type, speak, handwrite, or attach a photo of your working, translate a question into your language, and get instant AI feedback on written answers. Routes to /rank-booster/diagnostic.
Full-length timed mock tests. Step 1 is the same scope picker as Practice — board, class, subjects, chapters, with per-chapter topic narrowing and Add another scope for a mixed-syllabus mock (your board chapters plus an entrance-exam set, say) — alongside the same Filters disclosure and live "questions available" count. Step 2 picks a format — Minor test (15Q/20m), Chapter test (20Q/25m), Subject mock (60Q/75m) or Full mock (180Q/180m) — then launches the timed mock.
Spaced repetition of what you learnt, with a three-tier queue (48h / 7d / 30d) and Due-now / Next-24h / In-queue / Retired counters. Premium — a Lock chip routes free users to Upgrade.
A notebook listing every question you got wrong, deduped and grouped by topic with a wrong-count and when you last missed each. Its Wrong Answers drill starts a session that re-serves only those missed questions (optionally scoped to a topic) so you can redo and clear them. Routes to /rank-booster/mistakes.
Every topic shown on a read-only skill tree with a SmartScore badge (weak / building / mastered) and a legend rail breaking down the mastery distribution.
Revision is gated to paid plans. On the free tier its card and the Explore "Revision" tile both route to the Upgrade screen rather than opening the queue.
Choosing what to practise
Learn, Practice, Exam Prep and the Skill Graph all start the same way: you tell Rank Booster which part of the syllabus to draw from. It is the same scope picker teachers use to build papers, so what you see here matches what your school sees.
Pick your board, your class and one or more subjects. The chapters appear underneath, each with the number of questions waiting in it. Chapters showing no questions are greyed out. Use Search chapters to find one by name, or Select all to take a whole subject in one click.

Board → Class → Subjects → chapters, with the number of questions available in each chapter.
Want to prepare for two syllabi at once? Click Add another scope and a second block appears with its own board, class and subjects — your CBSE Class 12 Mathematics chapters in the first, JEE Main Mathematics in the second, practised together in one session. You can stack up to four, and collapse or remove any of them.

Mix syllabi in one session — school chapters plus entrance-exam questions, up to four scopes.
Revising one idea rather than a whole chapter? Click the chevron on a chapter card and it opens into a list of its topics, each with its own question count. Tick only the topics you want — the chapter then shows a dash and a count like (24 of 96), and the session serves those topics only. Topics with no questions are hidden, so anything you can tick will give you questions.
A chapter card in Rank Booster expanded into a topic checklist with question counts, a few topics ticked, and the chapter showing a partial-selection dash
Expand a chapter to practise individual topics instead of the whole thing.
The count under the picker is questions available, and it leaves out questions you have already answered correctly — so a chapter you have mostly cleared will show a smaller number than the chapter card does. If it drops to zero, widen the scope or switch to Revision or Mistakes to go back over what you have already seen.
Every subject stays selectable whatever your plan. On the free plan you can practise anything, up to 10 questions a day; unlocking a subject makes it unlimited, while the rest stay available as the same 10-a-day taster.
Generate a similar question
After any answer you submit in a practice or Learn session — right or wrong — a Sparkles "Similar question" button appears next to Next question. Tap it and the AI writes a fresh, board-style question on the same concept at the same level (it can include a figure or diagram where the topic needs one), so you can prove you have really got it rather than just seeing the solution.
You answer the new question right there in the chat — type it, tap an option, speak it aloud, handwrite it, or attach a photo of your working, exactly as in the main session. The AI grades it with a stepwise, board-style marking scheme (step-by-step marks that sum to the question’s total) and a clear verdict. From there you can ask a follow-up question to have it explain further, or hit Try another for a new variant on the concept — earlier rounds stay in the thread so you can look back.
On solution and feedback surfaces you may also see an Interactive Simulation button — it opens an AI-generated, hands-on visual of the concept (sliders, a live diagram and a guided explore → predict → test flow) so you can see how it works. Learn more in Interactive simulations.
