<p>Personally, I think the key is making sure you are studying for the actual test. How to do this? Do as many practice tests as you possibly can. Just get a bunch of different review books and do ALL of the tests. I actually just took the same tests this past June and got a 740, 760, and 790 respectively on chem, US, and math II. I cannot be of much help in prepping for chem b/c I didn’t do much (I was in AP and did all my studying then). However, for US, your 580 demonstrates that you don’t know your actual history yet. So the first thing you need to do is buy AMSCO and really memorize those facts. Unlike other history tests, the subject test is pretty much fact recall. If you want to work with better quizzes than the ones in AMSCO to check your knowledge as you read each AMSCO chapter (AMSCO quizzes aren’t very good), I recommend using [Kennedy</a> American Pageant 12e – ACE Practice Tests](<a href=“http://college.cengage.com/history/us/kennedy/am_pageant/12e/students/ace/index.html]Kennedy”>Kennedy American Pageant 12e -- ACE Practice Tests), these are the quizzes for the American Pageant textbook, which are all very good (I used these throughout the year in APUSH). Secondly, you need to buy a BUNCH of books and just do all of the tests. I think I did around 9 or so for US. I had the REM SAT US book, which I only used for practice tests, that I think had 6 (they were harder than the real thing, which was a good thing). I also had the 2 college board official tests, Princeton review, and a barrons. I do NOT recommend using these review books to learn content–they are much too general. However, once you have learn the content, do ALL the tests, and the facts will start to stick. Trust me, they repeat questions. Now for Math II, you got a 650, so you are starting out with a decent score. Personally, I skipped any content studying for this test and just learned form practice tests. My first question is, have you taken precalc yet? If not, that may explain some things. Second of all, are you programming your calculator? You are wasting time memorizing formulas–this is math after all, and collegeboard EXPECTS you to program (hence, they don’t clear calculators). I recommend putting all formulas in your calculator (personally, I don’t like programs, so on my Ti-89 I used notfolio and just put in different formula sheets…geometry, trig, probability, etc.). Also, if you are not already using a Ti-89, I high recommend it because it is a time saver. Ok, so for Math II, I did ~15 practice test. I have an old barrons reviewbook. GET YOUR HANDS ON THIS! This was the best prep I had. The book had 10 practice tests all of which were hard but covered questions that actually appeared on the test! These were soooo useful for me! I also had the official 2 college board tests, and Princeton review. I doubt they still make the old barrons book w/ 10 tests (today, barrons are more content based than test based), but ebay it and seriously try to get it! REM might have a good one too, but I personally didn’t use it. When you get things wrong, the key with math is to know why and fix. Also, make sure you save college board real tests for the end, because you can use them to get a REAL number of how you will likely do on the test. Finally, on math II, do NOT be afraid to skip. The curve is really in your favor, you can skip at least 15 on almost all tests and still break 700. That being said, all 3 of the tests you are working on actually have awesome curves, so seriously, don’t be afraid to skip. I hope that helped!</p>
<p>But really, summary of what I said, just do practice tests! Except for the US, where you do not know the content yet, just keep doing test after test! My first 2 subject tests I took (bio and math I), I only got in the mid-high 600s. This is because I focused too much on content! Do practice tests!!! It will work. Sparknotes/cliffnotes also have a bunch, personally, I am not a fan because they are not realistic at all and I hate doing things of the computer, but that’s just me!</p>
<p>Hope I helped somewhat :)</p>
