JEE CBT Simulator — Free PYQ Practice in Real NTA Format
Tired of staring at a PYQ PDF with a stopwatch on your phone? Or fighting through ads and subscription popups on a so-called “free” mock test? Attempt JEE Main and JEE Advanced past papers in a real CBT interface — same timer, palette, and mark-for-review controls as the NTA exam. Two clicks from this page to a mock in progress.
Why practising in real CBT format matters
JEE Main is a Computer-Based Test conducted by NTA. JEE Advanced is also CBT, conducted by the IITs. The day-of-exam interface — the timer in the corner, the question palette on the right, the section tabs at the top, mark-for-review behaviour — is identical across both exams. Students who practise on PDFs lose 5–10 minutes on exam day just adjusting to the layout. A real CBT simulator removes that adjustment cost.
What you should look for in a JEE CBT simulator: matching timer behaviour, a real question palette (not a fake one with just numbers), proper mark-for-review states, section switching that doesn't lock you in, and a result page that actually tells you something useful. PracticeJEE is built to match all of these.

FAQ
JEE CBT simulator — frequently asked questions
What does CBT mean in the context of JEE?▾
CBT stands for Computer-Based Test — the format NTA uses for JEE Main, and the IITs use for JEE Advanced. Instead of pen-and-paper, you sit at a computer with a fixed timer, a question palette on the side, mark-for-review controls, and section-wise navigation. Most students who do well on JEE practise PYQs in this exact format so the real exam interface feels familiar on the day.
Is the CBT simulator on PracticeJEE actually free?▾
Yes. You sign in with Google (no phone number, no email forms, no payment details), pick a past paper, and start. There are no ads, no popups, and no paywall on the result page. We monetise through an optional Pro plan that unlocks every chapter and unlimited mocks, but the CBT simulator and PYQs are free.
Which previous year papers can I attempt in CBT format?▾
JEE Advanced 2026 Paper 1 and Paper 2 are live in the CBT simulator. JEE Main full-length mocks are also available in CBT format. We add more years as we extract them.
Does the simulator match the real NTA / JEE Advanced interface?▾
Yes — section switcher, question palette with status colours (answered, marked for review, not answered), mark-and-next behaviour, language toggle, and auto-submit on time-up. The questions are original (we don't redistribute NTA's content) but the UI behaviour mirrors the official CBT.
Can I upload my own PYQ PDF and attempt it in CBT format?▾
Not yet. Today we host curated papers extracted from official sources. Custom PDF upload is something we're considering — it's a real ask from the Reddit JEE community. If this matters to you, email support@sdmai.org and tell us which papers; it helps us prioritise.
How is this different from Testbook, PracticeMock, or other JEE platforms?▾
Three differences students notice: (1) Truly free — no subscription gate on the result page, no dark patterns nudging you to upgrade mid-attempt. (2) Two clicks from URL to mock-in-progress — no phone number, no ads, no forms. (3) AI explanations on every wrong answer after submission, not just a static solution.
Does the result include analysis or just a score?▾
Both. After you submit, you get: total score, subject-wise accuracy, chapter-wise accuracy, time-per-question patterns, your weakest topics ranked, and an AI explanation for every wrong answer. The result page is free — no paywall.
