SAT Reasoning EBooks

[Aeus]

has anybody here any useful ebooks for the sat reasoning?

I've read "Cracking the SAT" from princeton review.
done some kaplan practise tests.

I got problems on Reading Comprehension on larger passages.

Also forgot to buy the official collegeboard book, anyway now its too late because it won't be shipped in time.

but there are still two official collegboard practise tests available online.

read the strategies on princeton book, do its problems, then read barron's strategies if you have one. then start doing real practice tests from collegeboard
