Does anyone have any recommendations that I can use to study for all my class subject?

There sadly is none BUT there is "Smart Studying" and that is a method to help you help yourself study :)

Explanation:

Studying smart essentially means learning how to learn. This includes how to learn faster and more efficiently, while retaining information for longer. An example of studying smart is study in short chunks. Short study sessions help the synapses in your brain process information much better than lots of information in long sessions.
