My University Life(注意大写)

Today, I‘ve spent a whole evening studying with my roommates in the school library of my university.(今晚还没过完吧？用whole evening不太好) But why? I could have stayed in the dormitory watching movies and eating snacks as I wish. Well, the truth reason is that the mid-term exam is coming!!! Now I don't have no time to complain about how difficult the exam will be but try my best to let myself not fail pass it. Once I failed, I will have to restudy the course which I failed with the junior and take another exam . I believe it is the most horrible thing in the world. And CET-6 is coming , too. What an annoying April.!(感叹句请加感叹号O(∩_∩)O）

我的自我介绍（“自我介绍” is better according to the content of your article ）

大家好！
我的名字是 Tim，今年19岁. （If you want to introduce your age, use “今年XX岁” will make your language sound cute, because you are still young O(∩_∩)O）
我住在西班牙. 那是一个伟大的国家！
我喜欢中国的语言，因为它是非常漂亮，（是）我喜欢的书写系统！ (What do you mean? writing system?一脸懵逼+_+)
我想讲汉语我想是因为我想广交朋友.
晚上好给大家（晚安）！
