
Try addressing all of these concepts on a separate sheet of paper. If you don’t have enough
time to address all of the concepts, try to answer the ones that seem difficult for you.
Review your notes. Try to summarize the information from each page of the notes on
another sheet of paper.
Look over the resources
Reread or skim the reading assignments, making sure to notice the pictures and diagrams.
Try to create and take your own test.
Study aloud or with a friend.
Get a parent or sibling to quiz you.
Rewrite/reorganize your notes.
Make flashcards for the Scientific Method parts and vocabulary.
Start studying NOW!!! Set aside time each night to study until the test.
