Overview

ISRO Preparation

Taking mock tests is not optional for ISRO preparation — it is essential. The difference between knowing a subject and performing under exam conditions is significant. In ISRO's 120-minute paper with 95 questions and negative marking, time management and question selection are as important as technical knowledge. Mock tests build both.

BTechTutor offers free ISRO pattern mock tests for ECE, EEE, Mechanical, and CS disciplines. Each mock test follows the exact ISRO pattern — 80 technical questions (Part A) and 15 aptitude questions (Part B), 120 minutes, with 1/3 negative marking. Access links are below.

How to Use Mock Tests Effectively

  • Take your first mock test at the 4-month mark of preparation — even if you feel unprepared. The result tells you exactly where to focus.
  • Simulate real exam conditions every time — 120 minutes, no breaks, no checking notes. Half-hearted mock tests give misleading performance data.
  • Analyse every mock in detail — identify which questions you got wrong and whether it was a concept gap, a calculation error, or a question misread. Each category needs different remediation.
  • Track your mock scores over time. A graph of your performance across 8 to 10 mocks shows whether you are genuinely improving or just getting familiar with the same questions.
  • In the final 4 weeks, take 2 to 3 full-length mocks per week. This builds stamina for the actual exam and reveals any remaining weak areas.
  • For the aptitude section (Part B) — practise reasoning questions daily for 20-30 minutes from 4-6 weeks before the exam. This section is highly scorable with focused practice.
