The written test — Missouri Permit Test
The written test on the Missouri permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.
The rules
The Missouri written test is 25 multiple-choice questions and you must answer 20 correctly to pass.
Twenty of twenty-five leaves room for five mistakes and no more. That margin is why guessing is a poor plan.

On the test
How many of the 25 written test questions must you answer correctly to pass?
20 questions. Twenty of twenty-five leaves room for five mistakes and no more. That margin is why guessing is a poor plan. Missouri Driver Guide, p.2: “You must correctly answer 20 questions to pass the test.”
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.
