Highlight key words, especially scientific vocabulary know these terms!! 3. Make flashcards, make a quizlet, find some way to quick quiz yourself! 4. Look over warm ups posted online warm up questions are VERY similar to test questions. 5. Utilize tools at your disposal: teacher website on the unit page, at the bottom, is the unit review section.
