The present study is necessitated by the fact that most teachers concentrate on how to convey subject matter to their students and do not advise them about the proper way of revision.Besides, most of our students, we assume , do not know how to revise properly. Yorkey,R.C.(1970:210) points out that revision does not mean to reread the textbook or to memorize facts and formulas at the last minute.He recommends that the best way of preparation is to review briefly the material that we have reviewed during the preceding days.He advises the students to relax , preferably by going to bed early.
