I have this "shortcut" from a book regarding verb prefixes but I feel these are not informative enough.

Like how does „bronić” become „obronić”

How am I supposed to know if the perfective for „pisać” is „napisać”, and not „zapisać”, or „upisać”, it says completion in this list

I'm really struggling keeping up with these prefixes and converting the imperfectives to perfectives.

Pomóż mi, proszę!
