Hi Sameer,
Please make a schedule for all your subjects. Solve as many previous year question papers as possible. Make short notes of definitions and formulae for quick reference. Closer to the dates, go one subject a day wise and ensure you cover as much as possible. Stay focussed, cause your preparation days are numbered but results are permanent. So the more hard work you can put in, the more you do better and ensure you get good results.
All the best!
