So people learn very differently and there is not a correct way to study. If you are a memory person then I would do flash cards. If you are a sports type person then I would say study while bouncing a ball. If your teacher lets you have music make a playlist and study while listening to it. Also if you make up rhymes or saying for things you are more likely to remember them. If you are artistic then draw pictures to help you remember certain things. Also peppermint helps you remember things. Lastly study before you go to bed and get at least 8 hours of sleep before the test. This will put what you studied into long term memory instead of short term. Lastly don’t stress to much because it’s harder to remember what you studied when stressed.
GOOD LUCK ON YOUR EXAM!!
