If you're a student 1 classes, you have probably experienced many moments when it was hard to make yourself settle down and study, even when an important exam was coming up.
If you're like most students, you put off studying until the very last minute. The night before the exam, you'll stay up all night cramming, getting little or no sleep. In the morning, you'll drag yourself out of bed, and go into the exam feeling 2. You'll find it hard to focus or think, and you'll be cursing yourself for not starting to study sooner.
And it is not 3, that unless you're blessed with 4 brilliance, or you happen to know the subject matter 5 well, you'll probably do terribly on the test.
