I was able to improve my SAT score by 100 points (1340 to 1440) by using some of the strategies the author talked about. I would have never thought that I would ever be able to improve my SAT reading and writing score, but looking through the book really helps with understanding the techniques and shticks that College Board tries to use to trip people up, and overcome that obstacle. The book also has practice test walkthroughs that you could look through if you have the time and energy.
