Find out where you actually stand
Twenty questions, no account, no card. You will see your score, your four strand breakdowns, and what your wrong answers say about your thinking.
Linear Equations
What the engine reads
Answer the item and the engine names the thinking behind your choice, then moves the next item's difficulty.
The diagnostic is free and always will be
Nothing is gated behind a signup. Take it today, take it again in a month, and compare. If the free test is all you ever use, that is fine.
No account
Start the test in one tap. Nothing to create, nothing to remember.
20 questions
Same 4 strands and the same starting difficulty as the real TSIA2.
Adapts to you
Answer well and it gets harder. It finds the edge of what you know.
When practice alone is not enough
- FULL CURRICULUM
Lessons and practice across all 97 topics, sequenced so you are not guessing what to study next.
- UNLIMITED PRACTICE
Work a topic until it holds, with new items each time instead of the same ones back.
- GUMU
A tutor that asks you questions about your reasoning instead of handing you the answer.
- PROGRESS THAT STICKS
Your account keeps every attempt, so you can see what moved and what did not.
- RETAKE ANYTIME
The diagnostic stays free and unlimited whether or not you ever buy anything.
Passes are one-time purchases, not subscriptions. See pricing.
Purchases must be completed by a parent or guardian if you are under 18. The account and the progress stay yours.
Remedial math costs a semester you already paid for
The TSIA2 decides whether you start college in credit-bearing math or in a developmental course. Developmental courses cost tuition and take time, and they do not count toward your degree.
The test is not measuring whether you are good at math. It is measuring what you can do on one particular day, on a format most students have never practiced. That part is fixable.
Questions students ask
Really free. No card, no trial that converts, no "unlock your results" screen. You take all 20 questions, you see your score and your strand breakdown, and that's it. The paid product is the practice course you'd take after, if you want it. The diagnostic stands on its own.
