<p>This is a rather strange question seeing as everyone wishes to complete all sections of the ACT, however, I find that many times I am left with a few questions at the end of each section. I have heard many rumors that the most common scantron answer is "C". Is it better to answer all unanswered questions at the last minute with "C"s or random?? Does it even matter at all...I need every single possible point...</p>
<p>Don’t believe people who say that. You can find patterns like that when the answers are decided by a human being (because people tend to fail miserably when trying to be as “random” as possible), but these test answers are written by machines. I’m all for informed guessing. Instead of having 5 questions that you never even look at and can only guess on, have 7 questions that you can at least cross off a few obvously wrong answers before guessing at. 50% chance *7=3.5 right, but 20% chance *5=1 right. Even if you only cross off one or two answers, it’s worth it to not guess completely blindly!</p>
<p>According to Barron’s ACT 36, C is not the most common answer. Don’t fall for it lol</p>
<p>If you have questions left, it is best to pick one letter and fill in that bubble for all the questions you do not have time for. It may sound weird, but picking one letter instead of guessing randomly will give you a better shot at getting more questions correct. Choose either A, B, C, D, or E and fill in that bubble for each question you don’t have time to complete. Princeton Review calls this the “Letter of the Day.” I used the technique and it did help me quite a bit.</p>
<p>A,B,C,D,E should theoretically have equal probability. I am still amazed at how the answers to #22-25 on last year’s AMC12A math competition were all C.</p>
<p>I have to disagree with efirestone14. Your expected value from guessing is still (1/5)*the number of questions you guessed on. Unless you were taking the 2012 AMC12A, it’s very unlikely guessing any one letter will help that much.</p>
