Answer explanation

During the PSAT, if you have NO idea which answer to pick for a question, you should

• choose a pattern and stay with it.

• pick a different letter each time you have to guess.

• Choose a letter and do NOT waste time worrying about what letter to pick.

Answer explanation

Most quizzes are designed on a computer and there is an option to randomize the order of the possible answers (this quiz has that setting). If it is random, you cannot figure out the logic (i.e. it should be A because there has not been an "A" in 8 questions).

If a human makes a test on their own, there may be some psychology that you could use to look for patterns.
