Hello Aspirant,

See I would personally recommend you to first of all focus on clearing backlogs. This is because until and unless you clear the backlogs you would not be able to build the concepts of upcoming syllabus because until and unless your base would get stronger you could not develop the understanding of other concepts.

So for now just put al your focus towards clearing the backlog and try to maki it bit faster but faster doesn't means that you just complete them, you will have to understand all those topics and then only it will benefit your otherwise it will be only waste of time. So focus on those chapters that you had left earlier and have proper understanding of them then only proceed further.

I hope this information helps you.

Good Luck!!
