text: i can't concentrate in class, who can give me some tips? i'm a university student. firstly,i consider you have to know the reason for your un-concentration. ( sleepy or not interest in the content .....) secondly, you can find ways to solve them according to the reasons. it is simple for a sleepy student. but it is rather difficult to solve others . here i'd like to enjoy my experience on other problems, that is to set a goal for you in a period of time, thus you follow it actively.it is very useful.
