Would be extremely happy to help :)

The first thing you need to do is start as early as possible: the more the time you have in hand the better it is. Start preparing slowly with the basic topics from every subject and try to grasp the concept. You should have an in-depth knowledge about the fundamentals because that is what everything later is going to be based upon.

Chalk out a schedule for yourself. Make a 2 year plan. In the first few months you have to get yourself in a habit of studying for 8-9 hours per day. Join a good coaching institution if there be the need. Good institutions can guide you and also provide you with ample of materials to study from. Solve online mock tests and past year papers. Within the end of one year, you should have finished with 90% of the syllabus. Take the rest of your 6 months to complete the remaining syllabus and revise. The last 6 months are your brushing up months. Polish your skills by recognizing areas of improvement through continuous practice of exams. While doing all of these, make sure you have fun and enjoy the most because nothing is as victorious as a happy mind.

The amount of efforts and amount of dedication you out in shall correspond to results you achieve.

As per many toppers, the important aspect is time management where many of them devote 6 hours daily for studies and 1 hour for revision and mocks of the chapters dey cover.
