The passing score in Massachusetts is 72 percent. It means you should answer at least 18 out of 25 questions correctly to pass both this practice test and the real RMV test.
The safest tactic, however, is to aim for a full score on each RMV practice test.
Take as many tests as you need to feel comfortable with all answers. Learn by your mistakes. If needed, use the RMV Driver's Manual and read up on the facts.
The more practice tests you take, the more you cover of the Massachusetts Driver's Manual and the easier the real test will be.
Permit practice tests work best as a supplement to the Massachusetts driver's manual, not as a substitution. Use the practice tests to check your progress and find areas you need to improve. Go back to the driver's manual focus on understanding, not just memorizing answers.
