Groupon offers 12 months of access to any one BenchPrep Test-Preparation Course for $19. That's tied with last week's mention as the lowest price we've seen for any BenchPrep course. (They're valued at up to $200, and many are on sale on BenchPrep's site for $99.) This cross-platform education site preps students in GMAT, LSAT, and other academic fields through discussion boards, quizzes, and practice tests. You'll receive a credit that can be redeemed for the eligible BenchPrep courses listed here. They can be used on Android, iPhone, iPad, and computers. The course is online only and is valid for 12 months after activation.
