Between Destroyers and Achiever.. which one have more practice test?? Please advise..Thanks!!

destroyer has 0 tests (lots of Q's for GC, Bio, OC, and QR in a spiral-bound book)

acheiver has 3 tests (computer based; www.3tquest.com (http://www.3tquest.com))

estroyer is a teaching tool not a practice teset. Use the destroyer before you even start with topscore or achiever. Once you understand alll the questions in the destroyer you should breeze trough top score and achiever.
