Any good methods to study? i really want to pass my test tomorrow at least a b or c but every time i study i always get a c ; (

Use flashcards
Read out loud 
Use graphs or diagrams
depends on what type of test

Just get stuck into it, if you like music and it helps you focus, listen to soothing music. Dark chocolate is also a great food to help your brain (not joking), depending on how many subjects you are studying for, do not study for more than 1 hour for each until having a break... Then repeat this process until you are satisfied... Good luck mate!
