Wanna achieve 65 out of 80 in maths boards

Average in school exams(35 out of 80) not bcz I'm stupid but bcz my stupid school just gave a single prep off for maths.

Anyways chem went good ,phy was shit(expecting 65). So scoring 85 in maths is of utter importance to me. The problem is that I've lost focus. I was quite energetic in chem and phy but maths ,idk man I shopping and procrastinating. Till now I've dome ncert of all chapters except 3 which I'll be dome with tonight. I also did some imp ques of all these chapters from ncert. Initially I planned to solve loads of pyqs but now I'm only gonna have 2.5 days to do so.

Anyways don't mind my yapping, I just wanna know if I can still get 65 out of 80
