Tips on taking exams
The following are a few study tips for high school students and college students, which will help you answer your exam papers with confidence.
_________
It is better to have all the study materials available to you before you start reading. This not only includes your texts and notes but also the previous years’ notes and things like a dictionary and reference books. This has two advantages. Firstly, you do not need to break your concentration (专心) by searching for books. It saves time. Secondly, it gives you a feeling of being prepared for the exams, as you have all the necessary things and the only thing left its to start studying .
__________
The most common mistake that students make is that they start studying a day or two before exams. You can’t revise (复习) all the notes if you study only two days before exams. Therefore, what most of the students do is study only the “so-called” important points. As a result , even if the test paper is easy , you get a low score only because you don’t know the entire syllabus （课程提纲）. So start studying at least a month before the exams.
_________
If you have descriptive subjects, do not just remember the answers. Try to understand what you are reading, for this is the best methods for good recall at the time of exams. The major disadvantage of reciting is that if you forget one word of the answer during your exam, you tend to go completely blank. On the contrary (相反地), if you understand the subjects well, you can write the answer on your own at any time. For exams like math , practice at least five sums every day. Math cannot be learned in a day .
________
The last tips is to study when you are in your best mentally active state. Some people are comfortable studying in the early morning, while some like studying at night. Find out the time when you are fresh and relaxed and choose that time for your studies.
