<p>I want to buy some books for preparing my subject tests and I found on the internet some bargains. However I don't want to purchase something which would not help me at all. For example, are the following books good: </p>

<p>What about the kaplans?
Basically, have subject tests changed since 2000?
I'm sure I'm gonna take maths and physics because I'm good at them and their curve are quite lenient. However I would like to take a third test but I don't know which one.</p>
<p>Biology: I know everything in my native language. I would have, therefore, to learn just the translations.</p>
<p>Chemistry: I know the subject and there's no problem of translation because the words are mostly the same but I'm afraid of the questions about the security and functioning of a lab which are too wordy. Moreover it could be harder to have a 800 in account of a harsh curve and some tricky questions. Please correct me if I'm wrong.</p>
<p>World history: As everyone I know some stuffs from school but I'd need to learn a lot of things additionaly. I'm sure it would show something else to admission officers but that's not the point (actually I don't care). I think, to my own intellect, that knowing the world history could be more benificial even though I may not be able to have a 800. Is it worth to prefer taking WH to having a good score in chemistry or biology. </p>
<p>So please enlighten me about the pros and cons of each test. I have three dates up to the deadline (even 5, counting on June and march). So I would be able to take more. I know that colleges usually require two tests but as an international I'm sure they would be more comfortable with several SAT scores than with some excellent grades from an unknown country. Tell me if I should consider another test.</p>
<p>PS: I'm gonna score at least 780, if not 800, in maths and physics if it can help.</p>
