Hourly Prep is the only one with a check in every row.
Start with the free diagnostic. Pay attention to the explanations: can you work through a similar problem afterward? Decide whether you want additional tutoring and a personalized routine.
How Hourly Prep works
Hourly Prep is built around short, interactive SAT and ACT practice. Start with the free diagnostic, which covers every section, and see an explanation for every answer. Daily SAT and ACT sets come with Premium. You choose a daily routine that fits around school and everything else.
Seasonal Premium is $90 for 12 months on the web, or $100 in-app. It adds personalized study, an in-app AI tutor, and daily SAT and ACT practice. Check Premium availability and details before deciding.
