I still do not know how to use a compound light microscope. please help.?

hello. i'm a college student and i am taking a biology course along with a lab. we are using a compound light microscope for every lab period, and I am still having a hard time using it. everyone in cl seems to get the slides right away and draw on the lab manuals their results. the professor is checking the answers this week and i am scared because i couldnt write down or draw anything. i thought about buying a cheap microscope, the ones that kids use, but i don't think it will help because it's not the same. please help me.
