How NEET UG CBT Simulation Works

NEET UG is set to move to Computer-Based Test (CBT) mode from 2027 (here is what has been announced so far), so many aspirants will walk into the exam hall having only ever practised on paper. The syllabus doesn't change, but the interface does, and under a multi-hour timer, interface friction costs real marks. NTA has not yet published the final NEET CBT paper layout, so this page explains how a typical NTA computer-based test screen works (NTA already runs exams such as JEE Main this way) and how this platform mirrors it.

The two paper formats this platform simulates

NTA has not announced the final NEET UG CBT structure. This platform simulates two formats based on the NEET pattern:

• 200-question papers (3 hours 20 minutes): Each subject is split into Section A (compulsory) and Section B (attempt any 10 of 15). You are not required to answer every Section B question — but once you've answered 10 from that section, the remaining ones are simply extra practice; they don't count against you either way.
• 180-question papers (3 hours): A more compact format with no optional section — every question is compulsory.

Both formats keep the same subject order — Physics, Chemistry, Botany, Zoology — with continuous question numbering from Q1 straight through to the final question, in the same continuous style that NTA computer-based tests use.

Reading the question palette

The colored number grid on the right of the exam screen (the "palette") is the single most useful piece of the CBT interface, and also the most misread by first-timers. Each color is a status, not a judgment:

• Not visited — you haven't opened this question yet this attempt.
• Not answered — you opened it, but left without selecting an option.
• Answered — an option is selected and saved.
• Marked for review — flagged to revisit, regardless of whether it's answered.

Why this platform exists in this exact shape

The goal isn't to look like a generic quiz app — it's to remove every "wait, how does this button work?" moment before you're sitting the real exam. That's why:

• The timer counts down in the same corner, with the same automatic submission behavior when it hits zero.
• The subject tabs and continuous numbering match the real screen, instead of resetting to Q1 for every subject.
• Your answer choice is saved the moment you select it — there's no separate "save and next" step to forget, mirroring how the actual system behaves.
• After submission, your paper is broken down by subject with a radar chart, so a 60% "physics" mark doesn't hide that you actually got Optics wrong four times in a row.

What to actually do with a mock score

A mock score by itself is just a number. It becomes useful the moment you open the review screen and read every explanation for the questions you got wrong — not just the ones you skipped. The score analysis guide goes into this in more depth, but the short version: track which chapters keep reappearing in your wrong list across multiple mocks, not just this one. A single bad mock means little. The same chapter showing up three mocks in a row means you've found a real gap.

How the score is actually calculated behind the scenes

Every question carries +4 for a correct answer, −1 for an incorrect one, and 0 for anything left unattempted — standard NEET marking, applied identically here. What trips people up isn't the arithmetic, it's assuming an unanswered "marked for review" question is somehow treated differently. It isn't. The system checks exactly one thing per question: was an option selected at submission time? If yes, it's evaluated as answered, review flag or not. The palette's "marked" color is purely a visual reminder for you — it carries no weight in scoring at all.

Section B's optional questions (in the 200-question format) are handled the same way: the system counts your first 10 answered questions per subject's Section B toward your score. Answering all 15 doesn't earn extra credit — it just means the extra 5 are evaluated as unnecessary attempts, so there's no scoring advantage to rushing through more than 10, only a time cost.

Common first-attempt hiccups, and what they usually mean

• "My answer disappeared when I switched subjects." It didn't — selections are saved per question automatically the moment you click an option. Switching tabs and coming back will show the same answer still selected; if it looks blank, double-check you're looking at the same question number, since continuous numbering across four subjects means Q51 (start of Chemistry) looks nothing like Q1 (start of Physics) despite both being "the first question of a tab."
• "The timer kept running when I switched tabs." That's intended: the clock is global across the whole paper, not per-subject, as in NTA computer-based tests. There's no way to pause it, which is exactly why the pacing habits above matter.
• "I couldn't tell if my exam actually submitted." A full submission always ends on a results/review screen showing your score breakdown. If you're ever unsure mid-exam, the palette itself is the fastest confirmation of state — it reflects your real, saved progress at every moment, not a cached view.
