Mathematics is one of the scoring sections of NDA, and it is a section you can practise on its own. Every Mathematics mock test here follows the NDA marking scheme (+2.5 Correct, −0.83 Incorrect, 0 Unattempted), so the score you see is the score that section would earn you in the real paper.
The question set is generated fresh for each attempt across Algebra and sets, Matrices and determinants and Trigonometry and the rest of the Mathematics syllabus, so you never repeat a paper. After you submit, you get a worked explanation for every question, your accuracy on this section, and the time you spent per question — the three numbers that actually tell you whether Mathematics is helping or costing you marks.
Trigonometry, calculus and analytical geometry recur heavily. This paper rewards mechanical fluency — drill until standard problems need no thinking.
A full-length paper hides where the marks leaked. Running Mathematics on its own for a week or two makes the weak topics obvious, because there is nowhere else for the errors to hide. Once your accuracy in this section is steady, go back to full-length mocks.
NDA scores this section at +2.5 Correct, −0.83 Incorrect, 0 Unattempted. Track every wrong answer and mark whether it was a guess or a genuine attempt. Cutting guesses is usually worth more marks than learning new topics.
Read the explanation for every question you got wrong and for every one you got right by guessing, on the day you attempt the test. A mock you never reviewed adds fatigue without adding marks.
Most candidates over-practise the topics they already enjoy. Work through Algebra and sets, Matrices and determinants and Trigonometry and the rest of the list in rotation, and use the subject-wise breakdown after each test to decide what comes next.
Yes. Choose NDA, then select Mathematics as a single subject instead of a mixed paper. The test is generated only from the Mathematics syllabus.
Questions are drawn from across the Mathematics syllabus: Algebra and sets, Matrices and determinants, Trigonometry, Analytical geometry (2D and 3D), Differential calculus, Integral calculus and differential equations, Vector algebra, Statistics and probability.
Mathematics is marked at +2.5 Correct, −0.83 Incorrect, 0 Unattempted, the same as the rest of the NDA paper, and the mock tests use exactly that scheme.
Yes. After you submit, every question shows the correct option with a step-by-step explanation. Explanations are only revealed after submission, so the practice stays honest.
There is no limit and no charge. Each attempt generates a fresh question set, so repeating the section does not repeat the paper.
Two sectional tests a week while you are still covering the syllabus, then a full-length NDA mock each weekend so the section is tested under real time pressure alongside everything else.
