(Hau) Writing about study habits

II am a student at Universiti Kebangsaan Malaysia. After my classes at my University I like study at home. After I study one or two hour, I will take a short break. I seldom study with my friends because I can’t concentrate my studies at all. I prefer to study alone. Sometimes, I prefer to study at night because weather is cold. I usually make notes when I study. It helps me easy to find the key works when I study. In a week I think I study about 7 to 10 hour. At the beginning of every week I make a study plan for the whole week. I must study hard to obtain excellent result.
