How to guess on a test
Answer the questions you know first.
You'll obviously want to answer as many questions as possible without running out of time. In addition, knowing the right answers to the questions above and below a tricky true or false problem can help you find a pattern.
Guessing based on a true or false pattern is better than just guessing randomly. When answering the questions that you know on a test that has a separate answer sheet, make sure that you skip the same questions on the answer sheet as you do on the test itself.
