Today, many university students cheat in the exam.They use small tips、cellphones even kinds of tiny devices to get good grades instead of studying hard. Why do they take a risk and hand in unreal answer sheets? AS far as I'm concerned,for students,some are lazy 、 unambitious and don't want to master the knowledge and enrich themselves,some can't plan their learning assignment properly.So they don't have a good grasp of lessons and of course cannot achieve high marks. To solve the issue from the essence,school should improve the attendance system and homework-check system to urge students to study harder.Then,school must continue to strengthen ties with parents.
