How often should students be tested? A recent survey shows that many teachers give students exams

once every few weeks-sometimes even once a week . Some students think that there are many advantages

in having frequent exams, believing that exams help them know how they're getting on with their studies.

Thus, they can improve their study method and make greater progress. However, other students complain

that exams break up learning rather than encourage it if they are set too often. This is particularly true if

they are given to the class in a nervous and formal atmosphere. As a result, some of them may lose interest

in studies. Moreover, students will have no time to have sports or develop their own interests if they have to

be busy making preparations for one exam after another.
