Knowledge exam — Texas Permit Test
Knowledge exam on the Texas permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.
The rules
A score of 70 percent or better is needed to pass any Texas knowledge exam.
The bar is a share of the paper, not a fixed count of right answers. That is why the same rule covers exams of different lengths.
You must score a grade of 70 percent or better to pass any knowledge exam
Texas gives three types of knowledge exam: Class C, Class M, and the Class A or Class B rules exam.
The paper matches the vehicle. A motorcycle rider and a truck driver are not asked the same questions.
There are three types of knowledge exams
The Class C knowledge exam is the one taken by all original driver license applicants.
This is the paper an ordinary new driver sits. The other two exist for motorcycles and for heavy vehicles.
Class C – Knowledge exam for all original applicants
The Class M motorcycle knowledge exam is waived for an applicant who completes a state approved motorcycle operator training course and shows proof.
The course already tests the same ground and tests it on a bike. Sitting the paper again would measure nothing new.
This exam is waived for applicants who successfully complete a state approved motorcycle operator training course and present proof of completion
If an applicant does not pass the knowledge and driving exams on the first attempt, the application is held for 90 days.
The file stays open so the fee is not paid twice. After that window the paperwork starts again.
If you do not pass the knowledge and driving exams on your first attempt, your application will be held for 90 days
After 90 days or three failed exams, a new application and a new fee are required.
Three misses is where Texas stops treating it as the same attempt. The fee starts again with the paperwork.
After 90 days or three failed exams, a new application and fee will be required
On the test
What score passes a Texas knowledge exam?
70 percent or better. The bar is a share of the paper, not a fixed count of right answers. That is why the same rule covers exams of different lengths. Texas Driver Handbook, p.7: “You must score a grade of 70 percent or better to pass any knowledge exam”
How this works
Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.
You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.
Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
What it costs
- One payment, once — not a subscription. Nothing renews and there is nothing to cancel, for an exam you sit one time.
- Free to start: a 10-question test and the first section of cards. No sign-up and no account.
- Paying opens the rest of the cards, unlimited full-length practice tests, and retests built from exactly the questions you got wrong.
- Every level up to Prepared — 3 tests passed in a row.
- Do the work, fail the real exam, and we refund you.
