Given below are some valuable tips from the top rankers that can help you succeed.
- Try to solve the previous year's question paper a minimum of three times as follows: First, try to solve every question while reading the subject for the first time. The second time, solve the book during revision. Finally, focus on star-marked questions. If time permits, solve the entire book again.
- Solve the supplementary workbooks as it has a good collection of questions.
- Make Short Notes and try to Include all necessary formulas, concepts, and unit conversions in your notes, and remember to update them regularly as you study.
- Gate Toppers always prefer to time themselves to build speed and accuracy, crucial for exams like CIL, ISRO, BARC, ESE, SSC JE, and NLC. Although GATE provides sufficient time, other exams do not.
