Recommended Practice with Previous Year Papers
For proper preparation, attempt at least the last five years of question papers of GATE EY. These papers can be utilized in the following way.
- Analysis of Solutions for Every Question: After an attempt on a paper, work out each answer step-wise with the help of the solution key. In case the questions are quantitative, devote attention to the logical steps used.
- Time Management Practice: Attempt every paper under timed conditions. GATE EY is usually full of lengthy questions, so practicing under the exam timeframe is very crucial.
- Weak Areas: After analyzing your performance, look for weak areas repeated frequently and do recommended reading or online courses to improve those topics.
