<p>I completed AP chemistry with a 5 and IB Chemistry HL with a 6. This year, I am not in a chemistry since I have taken every one offered at my school. I am going to take the Chemistry subject test in November. I want to review because I haven't done any chemistry this year. I am a senior, so I really need to do well on this test. I have never taken a subject test before. What do I need to do to review. Which book would refresh my chemistry the best. From what I understand, I should have learned all the chemistry, so what will help me get an 800 or close?</p>
