Take a full JEE Main style mock test with 25 questions each from Physics, Chemistry and Mathematics. Questions are drawn at random from every JEE practice set on CodingHumans, from kinematics and electrostatics to organic chemistry, calculus and probability. You get a section-wise score at the end.
How the mock test works
- 75 questions (25 per subject) with a 3-hour timer.
- +4 marks for a correct answer and −1 for a wrong one. Unanswered questions score 0.
- Answers stay hidden until you submit. The test submits itself when the time runs out.
- The real JEE Main paper also has numerical-value questions. This mock uses multiple-choice questions only.
- After submitting you see a section-wise score and an explanation for every question.

Tips for mock tests
- Take the mock in one sitting, with no notes and no breaks, so your score reflects exam conditions.
- Do a first pass answering only the questions you are sure about, then come back to the rest.
- After submitting, spend as long reviewing the explanations as you spent on the test. Note every concept you got wrong and revise it from the linked practice set.
- Retake the mock after a week. Questions are shuffled each time.

Five sample questions
Here is a taste of the question bank. Try them before you start the full test. The answers are hidden until you open them.
A solid sphere starts from rest and rolls without slipping down an incline of vertical height 7 m. What is its speed at the bottom? (g = 10 m/s²)
(a) √140 m/s
(b) 10 m/s
(c) √98 m/s
(d) 14 m/sShow answer
(b) 10 m/s. mgh = ½mv²(1 + k²/R²) with k²/R² = 2/5, so v = √(10gh/7) = √(10 × 10 × 7 / 7) = 10 m/s. More questions like this
Which compound undergoes the Cannizzaro reaction with concentrated NaOH?
(a) Ethanal
(b) Propanone
(c) Methanal
(d) PropanalShow answer
(c) Methanal. The Cannizzaro reaction needs an aldehyde with no α-hydrogen. Methanal disproportionates into methanol and sodium methanoate. The others have α-hydrogens and give aldol products. More questions like this
Which compound is optically active?
(a) Propan-2-ol
(b) Butan-2-ol
(c) Ethanol
(d) 2-Methylpropan-2-olShow answer
(b) Butan-2-ol. In butan-2-ol, C-2 is attached to four different groups (H, OH, CH₃, C₂H₅), making it a chiral centre. More questions like this
What is the nature of the roots of 2x² + 3x + 5 = 0?
(a) Real and equal
(b) Real and distinct
(c) Non-real complex conjugates
(d) RationalShow answer
(c) Non-real complex conjugates. The discriminant is b² − 4ac = 9 − 40 = −31 < 0. With real coefficients, the roots are a pair of complex conjugates. More questions like this
What is the effective atomic number (EAN) of iron in K₄[Fe(CN)₆]? (Fe: Z = 26)
(a) 30
(b) 34
(c) 36
(d) 38Show answer
(c) 36. EAN = Z − oxidation state + 2 × coordination number = 26 − 2 + 12 = 36, the atomic number of krypton. More questions like this
How to use your result
Look at your score per subject, not just the total. A common pattern is strong Chemistry, average Physics and weak Maths, or the other way round. Decide the order you attempt the subjects in based on that, and practise that order in every mock so it feels normal on exam day.
Frequently asked questions
Is this the official NTA mock test?
No. It is an original practice mock built from CodingHumans JEE question sets. NTA publishes official mock tests on its own website.
Does it cover JEE Advanced?
The questions are at JEE Main level with some Advanced-style concepts. It is good preparation for both.
