Grade 12 Science Exam Review Mr. Primmer's Fantastic Study Tips Have fun!!!! Take a genuine interest in what you are studying! Use the website, all notes, handouts, and videos given over the course of the unit. Reading over your notes is not enough to prepare you for the test. Quiz yourself, make flash cards, re-write notes/definitions. Re-write unit tests. Try saying your notes or explaining your notes out loud to a person or pet. Choose a study environment that is free from distractions (example: library, coffee shop, kitchen table). Make a study plan and stick to it! Book off at least 6 chunks of time and plan what you are going to cover each time. Example: half a unit per study session. Keep track of what you have studied, what you feel confident in, and what you are still not sure about. Use symbols to write this on the review sheet. Get a good night s sleep before the exam. Exam Tips: Have something to eat before the exam. Budget your time to make sure you finish the whole exam. Don t get stuck on one question. If you don t know how to do it, move on and come back to it, or do questions you know how to do first, then go back to the hard questions. Self Check List: 1. Have I read over my notes/textbook? (Rate 1-10 = ) 2. Have I quizzed myself on the terms/topics? (HINT: put a check mark beside topics that you are really familiar with, put a? besides topics that you are not totally sure about, and put an X beside topics that you don't know) (Rate 1-10 = ) 3. Have I re-wrote important concepts? (Rate 1-10 = ) 4. Have I wrote practise questions? (Rate 1-10 = ) Study Action Plan!!! 1. What grade do want to achieve on this exam? 2.
