I had parttmie-job after a long absence today. Because, I had some test, so I had to study. Though I had took a long holidays, I studied only the organic chemistry hard every days. I heard the organic chemistry's test is very very difficult.I liked the organic chemistry when I went to high school, so I thought I can like univercity's. But it was mistakes. Univercity's study is very very harder than high school. In a textbook,it was written I couldn't understand. So I read textbook every days. Then I came to understand gradually. And I came to like it a little. Therefore it's test was successfle. But, another test was very worth. Especially "Syoku to Kankyou" was too bad. I may cannot get it's unit...
