How to prepare this subject
- Check topic coverage. Work through the groups above and mark unfamiliar concepts.
- Learn and practise. Study one relevant reference book, then solve worked examples without looking at the solutions.
- Apply concepts. Use GATE EE previous-year questions to assess where you need additional practice.
- Revise and test. Create a short formula or concept sheet and reattempt questions you initially missed.
