What this paper looks like

A JEE Main paper is 75 questions in three hours — 25 each in Physics, Chemistry and Mathematics. What catches most candidates out isn't the syllabus, it's the arithmetic of negative marking: at +4 and −1, a blind guess across four options is break-even at best and a slow bleed at worst. This mock reproduces that structure so its pacing and score reflect the latest reviewed pattern.

Section B contains exactly 5 compulsory numerical-value questions per subject. Unattempted questions score zero, while a wrong numerical answer receives the same −1 penalty as a wrong MCQ.

Topics covered

Sample questions with worked solutions

These short examples show the style of reasoning used in the simulator. They are illustrative and are not a full practice paper.

Sample 1. A particle starts from rest and moves with constant acceleration 2 m/s² for 5 seconds. What distance does it cover?

  1. 10 m
  2. 20 m
  3. 25 m
  4. 50 m
Show answer and solution

C — 25 m

Use s = ut + ½at². Here u = 0, a = 2 m/s² and t = 5 s, so s = 0 + ½ × 2 × 25 = 25 m.

Sample 2. What is the pH of a 1 × 10⁻³ mol L⁻¹ solution of HCl, assuming complete ionisation?

  1. 1
  2. 2
  3. 3
  4. 11
Show answer and solution

C — 3

HCl is a strong acid, so [H⁺] = 10⁻³ mol L⁻¹. Therefore pH = −log₁₀(10⁻³) = 3.

Sample 3. If f(x) = x² + 3x, what is f′(2)?

  1. 4
  2. 5
  3. 7
  4. 10
Show answer and solution

C — 7

Differentiate first: f′(x) = 2x + 3. Substituting x = 2 gives f′(2) = 4 + 3 = 7.

Questions candidates ask

How many questions are in the JEE Main mock test?

75 in total — 25 per subject across Physics, Chemistry and Mathematics, made up of 20 MCQs and 5 compulsory numerical value questions each, worth 300 marks.

Does the mock test have negative marking like the real JEE Main?

Yes. Correct answers give +4 and incorrect answers cost −1, matching the current NTA scheme. Unattempted questions score zero.

Is the JEE Main mock test free?

Yes. The available mock tests are free. Some questions include automated explanations and review guidance.

Can I practise Physics, Chemistry or Mathematics separately?

The mock runs as a full three-subject paper with tabs, so you can spend your time wherever you like within the three hours — the same freedom the real CBT gives you.
