SAT help. Improving Crit Read and Grammar.

I would also like to add that a few years ago, according to a study, those who wrote in cursive generally had a better average score than those who printed :3

I've also found that by reading general books (not stephanie meyer type crap)from modern day to classics, will greatly improve your knowledge of grammar and such. I do a lot of my testing by ear (english wise) so if you have a wider field of overall readings, then you also improve your knowledge of grammar indirectly.
