- Understand the weightage: The first thing to be understood in mock tests is the weightage of the subject. First and foremost, focus on a high-weightage subject or topic, but that would not mean you lack any basic understanding of any subject with a lower weightage.
- Regular Mock Tests: In the current preparation strategy for the mock test, students take one full-length test every week, and over time, increase it to two mocks a week close to the test date. It is essential to analyze each test by identifying weak areas.
- Review and revision: Take time to review your mistakes after each mock test and revisit topics on which you scored lower. Use this to adjust your study plan.
- Timed Practice for Speed and Accuracy: Do questions in a timed fashion; try to mimic the real test environment, attempting to improve both speed and accuracy.
- Focus on the Balanced Numerical and Conceptual Questions: GATE PE would often comprise theoretical questions along with numerical problems. You should balance the practice of both kinds in every mock test.
