How the bank is built
Generated wide, cut down to only what's verified
Six AI models produce a large candidate pool. Every question then runs a three-stage audit and a hard deduplication pass — only what survives makes the bank. The result is a large, clean, exam-aligned set with zero repeats.
STEP 1
Generate
Six models — Claude, GPT, Gemini, DeepSeek and two more — generate across every NEET & JEE topic, so no single model's blind spots get through.
STEP 2
Audit
Three stages — correctness, NCERT alignment and difficulty calibration. Hard-tier questions go to human subject mentors. Failures are dropped, not patched.
STEP 3
Deduplicate
Every question is fingerprinted by its stem + answer-set and checked across the whole bank — within and across exams — so duplicates are removed before you ever see them.
STEP 4
Verify
What remains is the 1,03,885-question verified bank — audited, deduplicated, and mapped to specific NCERT chapters and sub-topics.
THE ZERO-DUPLICATE GUARANTEE
1,03,885 questions. Audited to 0 duplicates.

We don't just hope the bank is clean — we measure it. A fingerprint of every question (its normalised stem, its option set, and its correct answer) is compared across the entire bank, both within a subject and across NEET/JEE families. The latest audit returned 1,03,885 unique questions and 0 duplicate copies. You never waste a practice attempt on a question you've already seen.
