We are going to take the College Entrance Exams in about ten days. Therefore, many students still
don't know how to balance their study, rest and physical exercises while prepared for the Exams. They
usually devote too much time to go over their lessons, what results in poor health and low efficiency of
learning.
As the proverb goes, early to bed and early to rise make a man healthy, wealthy and wise. We'd
better leave us enough time to rest and sleep since it enables us learn our lessons more efficient. What's
more, a strong and healthy body is the base for our further study, future work and creative activities.
In brief, as we are preparing for the Exams, don't forget that rest, exercise and study were equally
important.
