I want to finish this year very closely to full grade for all classes.. But.. how do you study? Are you supposed to read what you've written and then remember it? For all of my 18 classes?? Or do I just study for a test?? Also, I have 2 books to read (actually I have a lot but only those seem interesting) do I remember every single name and year in that book (the first one is a book about Bulgaria and even though we are learning our history since 1st grade I still can't remember anything) What happens when you read the book, you go to school and remember that information till the book comes up as a question in some random Wednesday test that no one warned us about??
Also how do you learn for tests?? Do you just read everything you have in the notebook and just guess what will be on there??
I have never paid attention in class.. how do you do that as well??

How did I finish 10 years in school with nearly perfect grades and don't even know what to do?? If without studying I am very good, then with studying I have a chance of finishing full grade this year.
Helppp!!
