countrylovin, just go to FreeRice
to practice vocab. kind of fun, very useful, and for a good cause.
jclay, i have Getting into the ACT, it has two full-length tests including writing sections. I also have the Real ACT, all of those tests are different from the Getting into the ACT tests. As far as strategies, I think the ones in the Real ACT are better (or at least better explained and updated). It also explains the answers to all the questions in the practice tests, very nice.
