What is the most common answer on multiple choice tests?

Some one says its B and that is very incorrect. the real answer is C. One must remember that there are better strategies to use than which letter is statistically the most common. That can vary greatly from test to test. A better method is to go through the test 3 times. The first time, answer the questions you know the answer to. The second time, answer those that you can eliminate two choices, more if there are more than four choices. If you do this, you increase your chances of choosing the right answer from 1 in 4 to 1 in 2. The third time, answer the questions you weren't able to eliminate two of the choices for. Hopefully, this will only be 2 or 3 questions, and there might be some clues in the test itself that will help you eliminate one or two of the choices.
