About XamBaaz
- What is XamBaaz and who is it for?
- XamBaaz is India's free-to-start practice platform for Class 8–12. It is one place to learn every NCERT chapter, then test yourself with Subject Mastery Tests. It's for you if you're preparing for CBSE Board exams, JEE Main, JEE Advanced or NEET UG. It's also for parents who want a clear, honest view of their child's progress.
- Can my child use XamBaaz for both school exams and JEE/NEET?
- Yes — that's why we built it. NCERT is the base of CBSE Boards and the syllabus for JEE Main and NEET UG. On one platform, you practise chapter by chapter for school exams, then take Subject Mastery Tests that follow real board and entrance papers.
- What is a Subject Mastery Test?
- Once you have practised every chapter in a subject, XamBaaz unlocks the Subject Mastery Test. It is a 30-question, 60-minute test on the whole subject, at Easy, Medium or Hard. It follows the pattern of a real board or entrance paper. It shows if you are ready for the exam, not just for one chapter.
- How much does XamBaaz cost? Are there hidden charges?
- 1 Easy + 1 Medium quiz on every chapter stays free forever — no card, no time limit — plus a free Hard quiz when you score 70%+ on a Medium quiz (1 per subject), 1 adaptive quiz that climbs to your level, one MHT-CET paper, one JEE paper and one NEET paper in each Class 11–12 subject (the Easy ones in Class 12), the Daily Challenge and the chapter's Key Concepts revision card where there is one, up to 6 quizzes a day. So you can use XamBaaz without paying at all. To unlock the rest (all Easy and Medium quizzes, every Hard quiz and every other mock paper, with no daily limit), pay for a full year: ₹999 in Class 8–10 or ₹1,999 in Class 11–12 — launch offer prices, against a regular ₹2,999 and ₹4,999. No per-chapter fees, no auto-renewal and no surprise charges. One year from the day you pay. Your class stays the same till 31 March; on 1 April it moves up automatically and the rest of your year carries over. Teachers pay ₹2,999/year (regular ₹9,999) for all classes 8–12. Schools and coaching centres can unlock students in bulk with an institute code.
- What happens to my class and my paid year next April?
- One year from the day you pay. Your class stays the same till 31 March; on 1 April it moves up automatically and the rest of your year carries over. If you practise Class 9 today, you move to Class 10 on 1 April, on the same account, and keep your XP, streak and rank. If you are repeating a year, the app tells you about the move the first time you sign in afterwards and you can put it back in one tap. Class 12 accounts do not move up. Teacher accounts already cover Classes 8 to 12, so nothing changes for them.
- What are the Key Concepts revision cards?
- Every NCERT chapter opens with a Key Concepts card — a quick revision of the core ideas, key formulas and common exam traps before you attempt the quiz. 389 chapters across Class 8–12 carry one, free for everyone.
- How many mock tests and exam papers does XamBaaz have?
- XamBaaz has 115 full-length papers, all on a real exam timer: 17 full-subject Mastery Tests and 21 JEE Main and 21 NEET UG mock papers, marked +4 / −1 / 0 like the real exam; plus 24 MHT-CET papers and 32 CBSE board papers, which carry no negative marking — just like those real exams.
- Who built XamBaaz?
- XamBaaz was founded by Bithindra Biswas, an IIM Ahmedabad alumnus with 20+ years of industry experience who has also taught as faculty at IIT Bombay. XamBaaz is built in Mumbai. Its goal is to give every Class 8–12 student good, exam-style practice.
- Which board does XamBaaz follow?
- XamBaaz follows the NCERT syllabus. It is the base for CBSE and many state boards, including the Maharashtra HSC (Balbharati) syllabus for Class 11–12 science. Chapter numbers, titles and content match the official NCERT textbooks. The content is useful for JEE and NEET too, since both exams are mostly based on NCERT.
- Does XamBaaz cover the Maharashtra HSC board and MHT-CET?
- Yes. For Class 11–12 Physics, Chemistry, Maths and Biology, XamBaaz follows the Maharashtra HSC syllabus as well as CBSE. This includes extra HSC-only chapters that CBSE doesn't cover. There are also full-length MHT-CET mock papers at Easy, Medium and Hard. The practice is NCERT-based, so it closely matches the Balbharati textbooks used for Maharashtra HSC.
- Which classes and subjects does XamBaaz cover?
- XamBaaz covers Class 8 to Class 12 across 8 subjects: Mathematics, Science (Class 8–10), Physics, Chemistry, Biology (Class 11–12), Social Science, English, and Computer Science. Over 34,309 NCERT-aligned questions are live across 441 chapters. That makes 3,300+ timed quizzes — Easy, Medium and Hard, 6 on a typical chapter. There are also Subject Mastery Tests at the end of every subject in Class 9–12 Math/Science and all Class 11–12 PCMB subjects.
- Is there a mobile app I need to download?
- No download is needed. XamBaaz runs in your browser, like a website, in any Android or iOS browser. It is made for phones first, works on 2G networks and fits every screen size. If you want it on your home screen, tap Get the App: it installs from the site in one tap (no Play Store download), opens full screen like any app, and students get +50 XP the first time they open it.
- What is the XamBaaz Olympiad?
- A monthly online contest, free to enter, held on one Sunday each month, live from 11 am to 5 pm, in three categories: the Thinking Challenge for Class 8–9, the Problem Solving Challenge for Class 10, and the Competitive Thinking Challenge for Class 11–12. The questions are logical reasoning and data interpretation, the skills tested in CAT, the CUET General Test, bank exams and placement tests. For Class 11–12, the paper follows the BBA entrance exams (IPMAT, JIPMAT, NPAT, SET): quantitative ability, data interpretation and logical reasoning, and verbal ability. It is 20 questions in 30 minutes. Each month the top 3 in each category win exciting prizes, the topper wins a free year of XamBaaz, and one student from places 2–10 wins a surprise prize. Full syllabus: xambaaz.com/olympiad/syllabus. Next date, prizes and rules: xambaaz.com/olympiad.
- What is the best free app or website for JEE preparation?
- A good free JEE platform should give chapter-wise NCERT practice in Physics, Chemistry and Maths, with real +4/−1 negative marking, full-length JEE Main mock tests and chapter-wise progress reports. XamBaaz gives you all of this free to start (then ₹1,999/year for Class 11–12). Most chapters also have key-concept revision notes, and there are JEE Main pattern mock papers at Easy, Medium and Hard.
- Which is the best free platform for NEET preparation?
- For NEET, the most useful free platform gives chapter-wise Biology, Physics and Chemistry MCQs that stick to NCERT, with NEET-style +4/−1 marking and full-length mocks. XamBaaz covers all NCERT Class 11–12 PCB chapters with free Easy/Medium/Hard practice, key-concept notes and NEET pattern mock tests. It also tracks how well you remember each chapter. Free to start, then ₹1,999/year for Class 11–12.
- What is the best free resource for CBSE board exam preparation?
- CBSE boards reward knowing NCERT well. So the best free resource gives chapter-wise NCERT MCQs with explanations, and board-pattern mock papers. XamBaaz has 34,000+ NCERT-aligned questions across 440+ chapters for Class 8–12. It also has free key-concept revision notes and Subject Mastery Tests that follow the board pattern.
- How is XamBaaz different from Physics Wallah, Vedantu or Unacademy?
- Those platforms mostly teach through recorded and live video lectures. XamBaaz is for practice, not lectures — it's where you practise what you've learned. Every NCERT chapter has adaptive Easy/Medium/Hard quizzes, full-length mock tests marked just like the real exam, and instant reports on your weak topics. Inside every account, Genie shows our notes for any term and lists your own wrong answers with the concept to revise. One student plan (₹999 a year for Class 8–10 and ₹1,999 a year for Class 11–12) unlocks everything in your class: every subject and every paper for that class. Use it alongside any video course or free lectures you already watch; it does not replace teaching.
- Is XamBaaz the most affordable way to practise for JEE, NEET and board exams?
- XamBaaz is free to start. Then one student plan (₹999 a year for Class 8–10 and ₹1,999 a year for Class 11–12) unlocks everything for your class: every subject, every difficulty level and every mock paper. It covers CBSE and Maharashtra boards plus JEE Main, JEE Advanced, MHT-CET and NEET UG, with no per-subject or per-chapter fees. (Teachers get all of Classes 8–12; a student plan covers one class for the year.) Most coaching apps charge for each course, often tens of thousands of rupees. One flat plan for both school boards and entrance practice is meant to cost less.
- Does XamBaaz have adaptive practice and a full test series, or just static questions?
- Both. Adaptive quizzes change with every answer, based on your speed and accuracy, across three difficulty levels. Your level carries into your next attempt. Beyond chapter practice, there are full-length Subject Mastery Tests and JEE, NEET and board mock papers, with a real exam timer and real exam marking. Chapter-wise accuracy reports show which chapter to revise next — honest, with no fake streaks.
- What is Genie, and does it make up answers?
- Genie is the free study helper inside every XamBaaz account. Type a term, a formula or a chapter name and it shows the notes we wrote for that chapter — it never makes up an answer, and if our notes don't cover your question, it says so. Its My mistakes tab lists every question you got wrong, with the concept to revise. You can try it at xambaaz.com/genie.
Exams & Syllabus
- Does the CBSE board exam have negative marking?
- No. CBSE board papers give marks for a correct answer and take nothing away for a wrong one. So leaving a question blank is never better than attempting it. JEE and NEET work the opposite way, which is why board practice and entrance practice must be scored differently.
- Is NCERT enough for JEE and NEET?
- For NEET Biology it very nearly is, because most of the paper comes line by line from the NCERT text. For Physics and Maths, NCERT is where you start, not where you finish. Those need problem practice above textbook level, from easy to hard. That is what the Hard level and the full-length papers are for.
- What is the difference between MHT-CET and JEE Main marking?
- MHT-CET has no negative marking, so the right plan is to attempt every question. JEE Main takes away a mark for a wrong answer, so a blind guess costs you. If you practise both with the same scoring rules, you build the wrong habit for exam day.
- Can one syllabus cover school exams and entrance exams together?
- Mostly yes, because both are built on NCERT. The chapters a Class 11 or 12 student studies for boards are the same chapters JEE, NEET and MHT-CET ask from. What changes is how deep the questions go, and the marking. Practise chapter by chapter in the NCERT order, and one year of work prepares you for both.
Quizzes & Question Bank
- What does practice on XamBaaz look like?
- Every NCERT chapter has Easy, Medium and Hard quizzes — 6 on a typical chapter, since each level has enough questions for several sets that don't repeat. Each quiz has 8-10 random questions (10 in most classes, 8 in Class 8) and a 10-minute timer (15 minutes on Hard Maths and Science). It is marked like a real entrance exam (+4 / −1 / 0). XamBaaz remembers what you've already seen, so each attempt feels new.
- Does XamBaaz have long-answer (subjective) questions too?
- Yes — new, and live for Class 9 and Class 10 Maths and Science. Every chapter has board-pattern long-answer papers at Easy, Medium and Hard: 30 minutes, 15 marks, with 2-, 3- and 5-mark questions and exam-style diagrams. Write your answers on paper against the clock, then check them against the model solution's step-wise marking and tick the marks you earned, as a board examiner would. It is real exam prep: timing, presentation and the steps that carry marks. The Easy paper in every chapter is free; Medium, Hard and the 90-minute, 30-mark Subject Mastery written papers come with Pro.
- Will I get the same questions every time I take a quiz?
- No. XamBaaz tracks every question you have seen. It picks questions you haven't tried, or haven't seen lately, first. Options are shuffled and questions vary, so the same chapter feels different even after a few quizzes. You can usually take 2–3 fully new attempts at each level before questions start to repeat.
- How long is each quiz?
- Each quiz has 10 questions and a 10-minute timer — the same time per question as JEE Main and NEET. Hard quizzes in Maths and Science get 15 minutes, for the longer working. The timer runs on our server, so closing the tab does not pause it. Your answers save each time you change one, and you can go back to an unfinished quiz on the same device.
- What happens if I close the tab in the middle of a quiz?
- Your answers save automatically each time you pick one. Open the quiz link again and you continue where you left off. The timer keeps running on our server. You won't lose any answers.
- Can I choose which difficulty level to practise?
- Yes. Before you start a quiz on any chapter, you choose Easy, Medium or Hard. XamBaaz shows how many new attempts are left at each level, based on the questions you have seen. So you know when questions are about to repeat.
Scoring & Progress
- How does the scoring work?
- XamBaaz marks like the real exam: +4 marks for a correct answer, −1 mark for a wrong answer, and 0 for a skipped question — the same as JEE Main and NEET. Board-pattern and MHT-CET papers are different on purpose: neither has negative marking, just like the real CBSE and MHT-CET papers. The goal is to teach you when to answer and when to skip, not just to recall answers.
- Why does XamBaaz use negative marking instead of a simple correct/incorrect system?
- Because real entrance exams use negative marking, and practising without it builds bad habits. If you practise with no penalty for wrong answers, you tend to guess a lot, and can lose 15–25% of your marks in the real exam. Daily practice with negative marking teaches you when to attempt and when to skip. That habit is one of the biggest differences between average students and toppers.
- What progress reports does XamBaaz show?
- Your dashboard shows your accuracy in every subject for Easy, Medium and Hard, side by side. It also shows your strongest and weakest chapters, a 30-day activity map, and chapter stars for 90%+ accuracy. No feel-good numbers — just what you need to decide which chapter to study tonight.
- How do XP and ranks work?
- You earn XP for every quiz you finish, with bonus XP for strong scores and daily streaks. Your XP gives you a Current Rank among XamBaaz students across India. It shows on your dashboard, your home page and after every quiz. You also see exactly how much XP you need to pass the student just above you — often just one quiz. Your Current Rank counts every XP you have earned, so it only moves up as you practise; inside the app you also get a separate weekly rank, which resets each Monday. The top 5 by total XP appear on the XamBaaz home page, shown as a first name and an initial.
Privacy & Technical
- How do I sign in? Do I need to create a password?
- Sign in with your Google account — one click, no passwords. Opened XamBaaz inside Instagram or another app, where Google sign-in is blocked? Choose the email code instead: we email you a 6-digit code and you type it in right there.
- Does XamBaaz sell or share my data?
- No. XamBaaz uses your Google ID only to sign you in and save your quiz progress and results. We do not sell, rent or share student data with advertisers or third parties. Student data is stored securely and used only for your own dashboard.
- What stays free, and what do you charge for?
- We pay for XamBaaz with one flat yearly plan — not with ads, and not by selling student data. Free forever, with no card and no time limit: 1 Easy + 1 Medium quiz on every chapter, a free Hard quiz when you score 70%+ on a Medium quiz (1 per subject), 1 adaptive quiz that climbs to your level, one MHT-CET paper, one JEE paper and one NEET paper in each Class 11–12 subject (the Easy ones in Class 12), the Daily Challenge, Key Concepts revision cards on most chapters, your full progress dashboard and the public practice library — up to 6 quizzes a day. The paid plan (₹999 a year for Class 8–10 and ₹1,999 a year for Class 11–12 for students, ₹2,999/year for teachers) unlocks the other Easy and Medium quizzes, every Hard quiz, and every other full-length Mastery, Board, JEE, MHT-CET and NEET paper, with no daily limit. Schools and coaching centres can unlock students in bulk with an institute code. Plans are one-time payments — nothing auto-renews — and we announce any price change clearly and in advance.

- We care about getting every question right. If you find a wrong fact, a wrong answer key or a confusing question, tell us through the feedback link in the app, or contact us. We check and fix reported questions within 48 hours.
