Our verdict on Solo Prep

Solo Prep is a digital SAT study platform for students preparing independently. Its lessons cover Reading, Writing and Math, alongside vocabulary study, practice questions and full-length mock tests modeled on the Bluebook format. Students can use it on web, iOS and Android, making it a fit for learners who want practice and review available on mobile as well as web.

The free plan includes one full-length mock, an instant score, report and explanations, one lesson in each of Reading, Writing and Math, and Vocab Set 1. For additional tests, the one-time Mock Pass costs $14.99 for four full-length mocks, with score reports, a PDF and review of missed questions. Solo Pass costs $19.99 per month and adds three mock tests per month, 33 lessons and weak-spot reporting. At $29.99 per month, Solo Pass+ includes eight tests a month, 33 lessons, 1,000 words and unlimited bank questions. The monthly plans may suit students wanting regular practice; the Mock Pass is the lower-cost paid option for a defined set of tests.

Adaptive timed modules and post-test analysis are central to the product: the second module adjusts based on performance, while reports break results down by question type and skill. Missed-question review and weak-spot reports help direct follow-up study. Solo Prep is a reasonable fit for independent students who value adaptive mocks and mobile access, especially if a free test or four-test bundle meets their needs. Students seeking ongoing lessons and a larger question bank should compare the monthly tiers; support is listed by email.
