Is 90% still possible in class 12 pcm

Considering that my chem 1st book is complete and organic chem thoda thoda ata h

Physics 1st book is complete but 2nd book(excluding optics) is not well prepared and I haven't even solved a single numerical by myself in whole physics,only did derivations aur apne physics teacher ko numerical

Maths mai 1st book,integration(ch 7),vector algebra he kre hai baki sab ko chua bhi nhi

Is 90% in boards still possible or am I just delusional at this point

(Also pls suggest some ways to atleast get 1st division😭)
