    Word problems will take any shape, from asking you a direction of a particle in motion, to about scientists. I don't know about a list, but you can find everything you need in PR.

    What kinds of things should I focus on in PR for the word problems?

    does SAT 2 physics include chaos theory and superconductivity and some of other things that PR didn't mention?

    medio - do you mean Chem or PR?

    Wilchartermage - someone asked me this in a PM. I sent them this:

    Just know these points:

    Superconductivity - The complete (as in EXACTLY 0) absence of resistance in a substance (as well as a lack of internal magnetic field). Most commonly occurs in supercooled metals.

    In short - EXACTLY 0 Resistance, No internal magnetic field, and VERY COLD Metals (but NOT absolute 0, that was a trick answer on the CB book's test)

    Superconductivity was on the test I took as well, it was very similar in form the the question in the CB book but I've forgotten it. It was easy though, it only tests those concepts above.

    Chaos Theory - The complicated version: "chaos theory describes the behavior of certain dynamical systems – that is, systems whose state evolves with time – that may exhibit dynamics that are highly sensitive to initial conditions"

    The easier version: Chaos theory is the issue of whether or not it is possible to make accurate long-term predictions about the behavior of a system. The key postulate of Chaos Theory is that is is IMPOSSIBLE to make those predictions (well you can but they'd be worthless).

    A common example of Chaos Theory is also known as the "Butterfly Effect," where the originator of Chaos Theory proposed that a flap of a butterfly's wings could spark a chain reaction that started a tornado a thousand miles away, and thus it is impossible to make long term predictions of weather.

    Chaos theory is actually a lot more complicated (and very interesting), but that's all you should need to know. I can't possibly imagine the SAT testing chaotic dynamics, etc lol

    Good Luck!

    I mean Physics for PR. What should I do with the book to prepare myself specifically for the word questions?

    Flashcards (if you're not already doing so?) for facts. I didn't prepare for word problems any more than I did for the calculation problems...knowing the base concepts is key for both

    chem equals bad class

    physics equals OK class

    is PR all you really need?

    I used it for the May test (and I was in AP Physics) and did horribly ....<650.

    What about sparknotes?

    i got an 800 in chem, too, and I just did practice problems from prep books ie PR barrons etc.

    Thanks for the post.

    For chemistry, how important are solubility rules. they didnt show up on the ap test.

    They definitely appear on the SAT subject test, so know them well! For a good example of those sort of problems, check out the set of the in Section A of the official CB book's practice test. SN tests have quite a few of them as well :)

    Thanks. Are the practice tests in CB blue book same as the ones in the old "Real SAT Subject Tests"?

    When was it published? I however doubt it - since the tests are from 2000 or 2003 in the new one, and I think the Real Subject Tests is 1998?

    But to make sure, you could post the first question or two from it

    did u do the stuff off of collegeboard.com?
    if so, did u find it helpful?

    I did, because I did every official problem I could lay my hands on. They were definitely useful.
