CDS Full-Length Mock Tests
Dates, vacancies and fees can change. Always confirm on the official CDS website before you apply.
Mock tests are where preparation turns into marks. They train you to read fast, manage the clock, decide when to guess and stay calm for the whole paper. LearnFrenzy has free timed CDS tests with instant scoring, the correct answer and an explanation for every question, and a certificate with your score.

How the online mock works
- Timer: 1.5 minutes per question, shown before you start. The test submits itself when time runs out.
- Navigation: move between questions freely and change answers before you submit.
- Instant result: your score, accuracy, time taken, and right / wrong / skipped counts.
- Explanations: every question shows the correct answer with a short explanation – read them all.
- Certificate: download a certificate with your score from the result page.
Convert your mock score to the real CDS marking
The online mock gives one mark per correct answer and no deduction, so you can see your raw accuracy. The real paper is different: English and General Knowledge have 120 questions each for 100 marks in 2 hours (Elementary Mathematics has 100 questions for 100 marks), so each question carries 0.83 marks. Each wrong answer costs one-third of the marks for that question (0.28 marks).
Worked example: in the 50-question mock you get 36 right, 10 wrong and leave 4. On the CDS scale that is 36 × 0.83 − 10 × 0.28 = 27.22 out of 41.67.
Do this after every mock. It shows the real cost of your guesses and helps you decide how many risky questions to attempt on exam day.
Performance analysis: review every mock in 5 steps
- Accuracy by subject: note how many you got right in each section. Keep a simple table and update it after every test.
- Error type: mark each wrong answer as a knowledge gap, a calculation slip, a misread or a bad guess.
- Time: if you finished with time to spare, slow down and read more carefully; if you ran out, use the "two-round" method (sure questions first, the rest in round two).
- Revision list: write down every fact or formula from the explanations that you did not know and revise it within 48 hours.
- Retake later: retake the same mock after two weeks – the score shows how much of the review actually stuck.
A mock test schedule
| Time before the exam | Mocks | Focus |
|---|---|---|
| 4–3 months | 1 per week | Find weak subjects; sectional practice on them |
| 3–1 months | 2 per week | Full-length timing; revise from your mistake notebook |
| Last month | 3 per week | Exam-time practice (same time of day as the real exam), no new topics |
| Last week | 1–2 light tests | Revision only – sleep well and keep up light fitness training |
Exam-day lessons from mocks
- Read the question twice when it has "not", "incorrect" or "which of the following".
- Eliminate first, then decide: if you can remove two options, an attempt usually pays off; with no elimination, it usually does not.
- Do not get stuck: a long calculation can wait for round two – move on after a minute.
- Keep 5–10 minutes at the end to review marked questions.
Mock scores are a guide, not a forecast. Cut-offs change every year with the vacancies and the paper's difficulty. Aim for steady improvement and 70%+ accuracy across subjects, and check the official CDS notification for the exact pattern of your year.
