SAT/ACT/PSAT Kaplan Software

I am preparing for the SAT I exam and I was thinking if kaplan software:

Kaplan SAT/ACT/PSAT 2006 Platinum (Windows & Mac)

is a good preparation tool.

Does anyone knows?

In case if you have tried it, can you share your experience.

Does the testing service provide prior year ACT tests with answers similar to the SAT QAS serviice?
