Which are good for preparation of the SAT test?
And which are not very long? because I have to finish reading in a short-time.

I want to raise my score up to the 1300-1400 range (out of 1600), with at least 700 in math & 600 in c. reading.

Recommend me some study material that can help me out.

I am just wondering if the GED is equivalent to other tests like the PSAT, SAT or ACT or if the questions on the GED are way easier than the others.

Also, as far as I can tell, taking the placement testing at a community college sounds like it will be easier than the GED. Is this true? What is the placement testing called anyway… is it something I mentioned above & I just didn’t know it, lol?

What is the best way to score high on the writing section & math section of the SAT? Anybody who has taken the new SAT this year have advice for upcoming juniors?

Like they have the SAT test and then they have the SAT & Subject Test.

Does it matter which score we report back or does it depend on the college?

Thanks a bunch!

Please let me know all the possible SAT prep classes I could possibly take. I feel like everyone’s just stuck between kaplan and princeton. Maybe there are other types of good courses that people aren’t really aware of.

But while you’re at it, please let me know which one you would BEST reccomend. Kaplan or princeton? & why?
Also, if it is possible, just tell me your scores after you took that course and (if applicable) what colleges you made it into.

Thanks!
