<p>I think that how much you have to study is a matter of if you're studying stuff that isn't on the test that you love, or if you're 100% in it for the test. </p>
<p>I've always been an avid programmer and history lover, so I came into both the AP tests with a strong background. </p>
<p>My advice for AP Computer Science: </p>
<p>-Memorize the intricacies and minute details of Java. They'll be the main focus of the test</p>
<p>-Practice looking at loops and seeing what they do, looking at a for loop should be as natural as seeing it in English/Maths</p>
<p>-Barrons is an extremely good book for this test. Recommend 100%</p>
<p>-Look at old AP Comp Sci tests sold by Collegeboard (or given for free on their site). The questions on the real test don't deviate much from the practice. </p>
<p>-Do lots of practice. There are a bunch of really nasty tricks they'll throw in with casting and so such that seem intuitive, and take skill to avoid. </p>
<p>My advice for World History: </p>
<p>-Don't get a detailed understanding of the whole world. Its not necessary. The multiple choice looks at trends and causes. Reading lots of encyclopedias to get a "big picture" is a good idea. Always think about why things happen and how they compare when studying. </p>
<p>-Don't overestimate Native Americans (North, South America), they come up on the tests EXTREMELY sparingly (maybe one or two questions at max)</p>
<p>-Pick a part of the world and time to concentrate on. Good examples include: Ottoman Empire, Rome, ancient China, World War I. Almost all the free response will let you pick 1 out of 3 areas to work with. For the areas you choose to concentrate on, get a lot of details and facts. </p>
<p>-Get an overview of key events, and know interesting details. Be able to summarize at least one major world revolution, one or two labor systems, one or two empires, etc. </p>
<p>-AP World is a lot like studying for two tests. The multiple choice is all about details, trends, and the big picture. The free response is about being able to pick from 2 or 3 parts of the world, and get in lots of details. </p>
<p>-Wear bug spray. A tick can be very distracting, I know because one was on me while I was doing the World History multiple choice. TICKS CANNOT BE CRUSHED! The best strategy is to bring in a blow-torch while taking the AP exam, to destroy any ticks that get on your leg. While your leg will be so mangled that it will be little more than a charred stump, it will be worth it since the tick will be toast. </p>
<p>Also, if you have a disorder like ADD or ADHD, you can get extra time to take the test, or even a computer on which to type the free response. Read this for more details: </p>
<p>Just pointing that out :)</p>
