Hello Bheemaraj, there is no shortcut for cracking big exams like GATE, CAT, UPSC. You just need to study consistently each day and read through better study material. You need to just out in about 7-8 hours of planned study every day till the date of exam and that will be enough. The earlier you start the practice for gate, the best it would be. Don't just try to read everything, try to read little bit every day and don't leave one day's study to next because then it will keep piling up. Take about 7 hours of sleep to keep your mind healthy.
