Hi
Yes, of course you can. You just need to manage your time wisely. In the first few months of class 12 when the board exams are far, or during summer vacations, when the school syllabus is not rushing, try giving more time to class 11 syllabus. Make a proper time table, where you give sufficient time to all 3 subjects and all concepts. Also, keep doing past year questions of a topic parallely as you complete it wrt the CBSE level. This will strengthen your grip at each topic. Once a month, keep a day, where you just revise or go through any chapter/topic you feel needs revisiting.
