240 Tutoring vs Khan Academy Praxis: the deciding question
Start with which test you need. Praxis Core tests reading, writing and math and is often used for admission to teacher preparation programs. Subject Assessments test the content for the subject and grade you’ll teach. Some states use their own tests instead of the Praxis, and our tests by state page shows where to check. If you need anything beyond Core, Khan Academy won’t cover it.
What you get with 240 Tutoring
240 Tutoring sells a monthly subscription to digital study guides, each built around a specific test. A guide combines text, short videos, flashcards and quizzes. You start with a diagnostic, and a full practice test unlocks once you’ve worked through 90% of the guide. Its pass guarantee refunds up to two months of subscription if you meet its conditions, including finishing the guide, and still don’t pass. Some schools and education associations offer reduced pricing, reported at around $20 to $25 a month.
What you get with Khan Academy
Khan Academy’s Praxis Core prep is free with an account. A diagnostic builds a personal study plan aimed at the skills you got wrong, across Reading, Writing and Mathematics. It was built with ETS, the company that makes the Praxis. There’s no paid tier and nothing to cancel.
What it costs over time
Khan Academy is free however long you study. 240 Tutoring’s cost depends on how many months you subscribe: one month at the reported $39.99, two months about $80, three about $120. Cancel when you’ve passed. If you can get school or partner pricing, the monthly cost roughly halves. Exam fees to ETS are separate; our cheapest Praxis prep page covers the full cost.
Using both together
A low-cost plan: use Khan Academy for Praxis Core, then subscribe to 240 Tutoring only for the month or two you’re preparing for your Subject Assessment. You pay only while you need content Khan Academy doesn’t have.
Mistakes to avoid
- Paying for Core prep you could get free. If Core is all you need, try Khan Academy first.
- Assuming the guarantee is automatic. 240 Tutoring’s refund has conditions, such as completing the guide; read them before you rely on it.
- Forgetting to cancel. A monthly subscription keeps billing until you stop it.
Choose 240 Tutoring if
- You need a Subject Assessment or a state test it covers, and want to pay monthly.
Choose Khan Academy if
- You only need Praxis Core and want free, ETS-built prep.
