SAT and ACT prep that explains every answer.
Clarion is a virtual academy. All study is online and self-directed, at your own pace. There is no campus, classroom or scheduled class to attend, and the image shown is an illustration.
Choose the test section you need, study each skill the test actually measures, and practice until the reasoning makes sense, not just the answer key.
Creating an account is free. You only pay when you choose a section.
See how Clarion explains a question
Every answer comes with the reasoning behind it, including why the tempting wrong choices are wrong. Here's a question from SAT Math.
If 3x + 7 = 22, what is the value of 6x − 5?
- 5
- 10
- 25 (correct answer)
- 30
Clarion explains
You don't need to find x first. Double both sides: 6x + 14 = 44, so 6x = 30 and 6x − 5 = 25. Choice D is the trap: it's the value of 6x, one step too early.
