History test I need help AHHHHHHHHHHHHH

Gosh man. I hate school. this past week I felt so sleepy and I haven't been able to much work. I have an early out all next week and I don't have school of thursday and friday but still. I need to work on so much stuff and study for AP history. Any tips on how to actually contain info in AP history? I study and yet all the notes I take I forget.. Im in unit 6 and I have a test on the 18th....... Sad face.......
