I had heard about this before, but a tip from Love My Tanker at SpouseBUZZ reminded me: Free SAT and ACT test preparation software is available to military members and their families. This program is offered by a group of NFL football players and the company, eKnowledge. The Standard ACT and SAT programs are offered for free, and the Premium programs are offered at a substantial discount. Also, all the extra programs, including LSAT review, are offered at half price. The customer will pay the shipping and handling, which is pretty expensive: $14 for each ACT or SAT program ordered.
A more complete explanation of the offer is available at MilitaryHOMEFRONT.
