The legendary (and yet strangely elusive) "Xiggi Method," is solid SAT advice from a regular College Confidential contributor. There are nearly 1000 comments about "the method" -- to give you some idea of the level of status this advice has achieved.
Personally, I don't agree with everything Xiggi advises (e.g. I'm not sure you have to buy tons of SAT books. I did that; it didn't work.) But, I'd say that I agree with about 90% of the "Xiggi Method."
The method also includes a few interesting and unique pieces of advice, such as taking a few practice tests with the answers in front of you so you can study the correct choices. Hummmm.....interesting; I wish I'd tried that.
Bottom Line: I think the 15 page "Xiggi Method" is well worth taking the time to read.
