Hello koalak,

Well, lets looks at how much time you have.  You have about 3 and a half months to prepare.  I think this is enough time if you use it wisely and productively.

How? Well, first rank the sections (Reading, Writing and Language, and Math) from hardest to easiest.  Then crunch down of the challenging section while doing some of the other two each day.

For example, I have trouble with the Reading but have no problems with the math and writing.  So each day I do a reading passage and do a postmortem on what I got wrong.  Every Tuesday and Friday, I work on either a math or writing section to keep those high scores.

Hope this helps.  And if you have any questions or concerns, feel free to ask.

Thank you for your comment! :)

I have another question about the Literature part of the test. I'm having trouble understanding the language I guess of Lit, and like what the passages mean. Is there any way that I can improve in this area?

Thanks!

Try the videos where (I believe) Sal explains how to crack the SAT passages.  He does a good job in doing that.
