Howo complete maths ka practice book (12th)

So I'm a isolated maths exam candidate, to I was Judy a little confused about the practical book. Because like for pcb you're not supposed to fill up all the practicals, but only certain ones. Is there a similar thing for maths. Could yall let me know? Like is it a different no of topics to be covered for each jr college, or is it all completed(I am gonna ask a teacher still)
