Hello,

I hope you are doing fine, No there will be no problem if you got the admission. But you have to clear all your concepts that you missed. You can take help from teachers and your classmates to complete your missed syllabus. If you don't complete your missed syllabus then it would affect your 12th next year because most of the chapters in mathematics are based on the syllabus taught in class 11tth (If you took Science PCM). So you should cover your syllabus. Rest there is no problem.

I hope you find this information helpful. I wish you all the best for your future.

Good Luck
