Other test prep companies, like Kaplan, offer apps for the full array of standardized tests that can be used alone or in conjunction with a Kaplan course or other study materials.
5. eTextPrep: Though it's not an app designed for a smartphone or tablet, this new mobile service is simple and targets the activity woven into nearly every high school student's life—text messaging. Students receive three vocabulary words a day via text to help them prepare for the SAT, ACT, or an array of Advanced Placement tests.
Lynne Anderson, mother of four, launched the service in February after fighting a losing battle against her children's incessant text message use. The service, available on all major cellphone carriers, costs $7.99 a month on top of standard messaging rates. "We used to see text messaging as the bane of our existence," she says. "It became an, 'if you can't beat them join them' approach."
