Unfortunately, all too many students leave a question blank after they’ve spent a lot of time trying to solve it. If you skip a question immediately, you save yourself a minute that you can use to solve other questions, and you may need the extra time. What you don’t want to do is spend a minute trying to solve a question, and then leave it blank. Now you’ve lost 10 points and 60 seconds. An important skill you’ll be developing is learning to tell—at a glance—whether you should leave a question blank or not. If you can’t immediately decide whether you can do a question, skip it for now—you can return to it later. Got all that? Leaving a question blank means not trying it at all. Once you spend time on a question, you’ve got to guess.
