It's pretty good to see that you are working so hard to achieve your career goals. There is one tip I would like to tell you that always expect less time available for you to revise the syllabus. If you get more time think that you are fortunate, as per your preparation try to complete your revision by January, if you get another one month time to revise then definitely use it. But for your sake keep the month of February as a final step preparation to gain more confidence and do your best at the exams.

Good luck!!
