Hmmm... I used the Princeton Review a while back and then the Barron's Review before the test, and I've got to say that
PR didn't necessarily prepare me that well. The tests were... a little bit off from what the real test is like, so I wouldn't invest too much meaning into the grade from your practice test.
Try a test from the Barron's book, though. It's pretty old and I don't think they've released a new edition, but if you can find it at the library I do highly suggest leafing through it. It's pretty accurate in how the actual test is, so that would be a better test of your abilities.
And if you can't get it, uhm... a 670 isn't horrible, but I'm not going to comment on whether it's good enough because I honestly have no idea. You never know what kinds of scores highly selective colleges are looking for, and the most obvious thing to say would be to aim for 700+, but since this is a subject test it's kind of murky...
I do, however, know about your last question--cramming a language in 3 weeks is difficult and ineffective for those who haven't had much contact with the language, but since you've studied Spanish before I don't think it would be impossible. They're pretty similar, so if you could really study up on vocab. (I recommend flashcards!
) and a little bit more of the advanced grammar (french.about.com is the best), I highly suggest it.
But... for Reading, it could go either way. Reading requires A LOT of knowledge in order to answer the questions and guess the meanings of more obscure words. But, as I said, if you're pretty good with Spanish and you can get the gist of what most passages are saying, you should be fine.
