NEET FAQ

NEET UG comprises 720 total marks across 200 multiple-choice questions (MCQs), out of which candidates must attempt 180 questions across Physics (180 marks), Chemistry (180 marks), and Biology (Botany and Zoology, 360 marks).

Each of the four subjects (Physics, Chemistry, Botany, Zoology) contains Section A with 35 compulsory questions and Section B with 15 questions where candidates choose and attempt any 10 questions.

Every correct answer awards +4 marks, every incorrect answer deducts -1 mark (negative marking penalty), and unattempted or unanswered questions receive 0 marks.

The total examination time is 200 minutes (3 hours and 20 minutes), giving students exactly 1 minute per question to read, solve, and select responses.

ThunderTest offers 30+ full-length 720-mark simulated mock tests (neet-full1.html to neet-full30.html) alongside 30 individual subject tests (neet1.html to neet30.html).
