Doing geo independently

Okay so in my school there were some timetabling issues for me as 3 subjects i was considering were in one block and another block had no subjects i wanted to do. After speaking to the principal we agreed for me to sit into a class that is in the block where i have no subjects and work by myself on geography. I have a book, i have notes from the teacher of this class (its an art class but she taught lc geo in her last school) and also notes from a girl i worked with who did lc2025. Im doing physics, bio, maths, english, french and german (no irish) and hopefully all HL. I now have the rest of 5th year plus summer and my lc year to finish the geo curriculum but ive only done 2 chapters… bad i know. But its genuinely so difficult to stay on top of it without someone guiding me. And in lc itll be even more difficult as ill be studying a lot as well. Any tips would be so so helpful ty.
