Therefore, to implement this ISRO 2023 preparation tip, aspirants are advised to solve the GATE previous year's question paper from the past 10 to 15 years if possible.

Analyze Topic Wise Weightage

Applicants can boost their ISRO exam preparation by prioritizing important topics like Materials, Fluid Mechanics, Engineering Mathematics, Mechanics, and Production, among others, which carry 60 percent of the total questions in the ISRO exam.

In order to identify the high weightage topics for the ISRO exam, previous years question papers come in handy.

Choose Smartly- What to Skip?

This is one of the most important ISRO 2023 preparation tips aspirants need to understand to ace the exam. There are a total of 80 questions worth 80 marks.
