Does anyone know the right way to study because i have a big test coming up and i want to study the right

Writing stuff down helps you to remember stuff, make flashcards for important vocabulary, when using flashcards to practice mark each time you get it right or wrong to know which ones you need more practice with, use if you have any questions about what your working on, use quizlet for vocab flash card games, and look up practice questions online for the subject you are working on. 

I hate to tell you this but there is no real right way to study. Sorry. 
But there is awesome ways to study. 
First read over any notes you might have for that class that might be on that test. 
Second make note cards on questions you might have. 
Third try asking for help. Sometimes getting someone to help you memorize something is very helpful.
Forth (and last) go over your notes before the test. If it is right before the test or on the way to school. Do it it helps to have the marital in your head.
