Yes, you can, if you are able to finish off your syllabus by the month of December then you have another two months in your hand to do the revision. While doing revision don't let undue panick curb your confidence, work on the portions where you need some more attention and revise them every consecutive days. Practice the logical and conceptual questions and go through the previous years papers for proper time management. Avoid all the possible distractions, focus more, work hard and you will positively succeed.

Good luck!!
