I am going to study economics exam.Economics is the best lesson which i really love , but did not have time to study it.When you study economics , you use your brain. You feel that your brain is working . I really like this feeling.I understand that you should follow the economics lesson each day. In only one day you cannot finish the whole units.It takes long time and it is also hard to understand everything only in one night.After that i will never try to study in one night.I hope i can finish the whole chapters. Wish me luck.
