General Tips

Daily Study Schedule: Aim for at least 4-6 hours of focused study each day, breaking it into sessions with short breaks. Practice Regularly: Solve previous years' GATE papers and take mock tests to familiarize yourself with the exam format and question types. Group Study: Discuss topics with peers to reinforce your understanding. Stay Healthy: Regular exercise, proper nutrition, and adequate sleep are essential for effective learning.

By following this structured approach, you can build a solid foundation in electrical machines and power systems within two months, preparing you effectively for the GATE exam. Good luck!
