Hello,
I'm planning to buy topscore pro. I know it's 3 full length practice tests. does it also have detailed explanations for the questions or jus the 3 tests? thanks!
First of all if you're gonna buy it, get it from http://scholarware.com/ where it's $50, dont pay $80 for it on amazon.
(IMO) Each question comes with a solution, but I wouldn't call them detailed. Very few have explanations, the conceptual questions seem to be better then ones that require calculations, where the solution will be so abbreviated sometimes that it only shows the first and last step... which can be useless.
Don't get me wrong, you need to take practice tests, so get some. I cant afford to buy both the Achiever and Topscore so i have no opinion on Achiever, but they might have better solutions. Try to find out
