Kaplan is such a great product, I was worried about my brother and his up coming PSATs and SATs because he tends to procrastinate often and puts off studying for tests till the last minute. Thats why I was overjoyed to find this wonderful product that not only helped him study for his tests but it was also super easy to use. It also helped that the Kaplan was able to figure out my brother's weak points, and it focused mainly on those. However, its great that the program also covers various other subjects such as writing, biology, history, and more. I was able to even use this program my self as my math skills are not very great. After having looked all over the net for a way to help my brother out, I ran into various other products which didnt provide the much needed info that is needed to prepare for any placement test. So it was a relief that I found this great Kaplan SAT program for my brother. Over all I recommend this program for anyone who has a high school kid, the ease of use combined with the through review of various subjects really helps out. Not just for kids tho, Kaplan is also great software for us older folks who could always use a tune up from long forgotten subjects.
