Mississippi written test scoring: 24 of 30

The Mississippi Administrative Code, Title 31 Part 1, Rule 2.3, requires a grade of 80 percent on any and all tests issued for a permit and adds that the questions are taken from the Mississippi Driver Manual. That makes the threshold official even though the state never says how many questions it is measured against. The Driver's License Manual describes the Computerized Exam only as a multiple choice test based on the manual, weighted toward state traffic laws, safe driving rules and license requirements, and gives no count. The Driver Service Bureau's permit, Class R and frequently asked questions pages are silent as well, as is the state PEER Committee's review of the bureau's testing operations. So the percentage is the number to plan around, and any specific question count you see quoted for Mississippi came from somewhere other than Mississippi.

A passed Computerized Exam score stays valid for two years in Mississippi, which is unusually generous and changes how the whole path is planned: a 15 year old normally holds the permit a full year before the license, so supplying the fifty hour affidavit inside the two year window means never sitting the exam a second time. Let it lapse and you start again from the exam. Testing itself is in person only, at a driver license station, with no online option. The Driver Service Bureau bars every electronic device from the testing area, phones, ear buds and smart watches included, and anyone caught with one or caught cheating has the exam canceled immediately and cannot test again for six months. Appeals go to the bureau in writing within thirty days.
