Start mock tests once you have a workable first-pass foundation and can tolerate mixed-subject testing without it becoming random noise. Frequency should rise as the exam approaches: spaced mocks work well early on, while the final phase benefits from more frequent full-length simulation.

To review a mock properly, separate careless errors from knowledge gaps and from timing failures, list the three to five subjects that hurt you most, re-study those topics within 24 hours while the paper is still fresh, and feed the same weak areas back into your question-bank blocks.

What matters more, score or review? Review. A mock becomes powerful only when you analyse wrong answers, time loss, and weak subjects in detail. Do not jump to the next mock without reviewing the last one, do not treat percentile alone as the whole story, and do not let one poor mock wreck the rest of the week.

MedNext exam simulation mode runs 180 questions under 3-hour 30-minute timing, matching the real NEET-PG format. After each session you get a subject-by-subject accuracy breakdown and a list of chapters to revisit, each one a direct link to the notes.
