PrepScholar is one of the better-known online SAT programs, and it works in a way that is close to mine. You take a test, it finds your weak areas, and it gives you a study plan built around them. The biggest differences are price and scope. Here they are first, because that is usually what parents ask me about.
\$397

\$29
freepracticeSAT.com plan
Math only. One payment, a plan that runs to your SAT date, up to 12 weeks. Tests and results are free.
Full disclosure: I built freepracticeSAT.com. PrepScholar's details below come from PrepScholar's own website, checked on October 28, 2026.
According to PrepScholar, the online program includes:
They also sell live classes, starting at \$895.
That is a lot of material, and it covers both halves of the SAT. A student who wants one place to study everything, and who has a few months, can get a lot out of it.
freepracticeSAT.com only does math, and most of it is free:
The \$29 plan turns your own mistakes into a day-by-day schedule up to your SAT date: mistake days, basics days, Desmos days with video walkthroughs, full tests and review days. It rebuilds itself after every test you take. There is a seven-day money-back guarantee. There is no score guarantee, because I don't think anyone can honestly promise a score.
You can see exactly what the plan looks like on the sample plan page before you pay.
Both programs start from a test, but they look at it a little differently.
As PrepScholar describes it, its diagnostic finds the skill areas where you are weakest and builds a weekly plan of lessons and practice around them. That is a sound way to do it, and it is how most study plans work.
My site looks one level deeper. Every wrong answer choice in my questions was written to match a specific mistake. If a student picks $ rac{13}{2}$ instead of $8$ when solving $2(x-3)=10$, that choice comes from multiplying the $2$ by the $x$ and not by the $3$. The site records that mistake, and the basic skills under the question, every time it happens. Then the plan puts the mistakes that keep coming back, and the weakest basics under them, at the front. When you take another test, the plan is rebuilt from the new results.
Neither approach is magic. Both only work if the student does the work each day.
With six weeks to go, what matters most is not wasting days. Whichever program you pick, I would take one full test in the first two days, spend most of the next four weeks on the few skills that cost the most points, and take a full test every week to check the work is paying off. Leave the last week for official practice tests in Bluebook and rest. A long course is hard to finish in six weeks, so a shorter, focused plan usually fits better.

It can be, for a student who wants one program for the whole SAT and will actually work through the lessons over several months. For a student whose main problem is math, a math-only plan costs much less.
No. It is math only. If you need help with reading and writing too, use a program that covers both, or pair my site with a free tool for that section, such as Khan Academy.
Yes. The tests and results are free and unlimited. You only pay if you want the day-by-day plan, and the sample plan shows you what you would get.
