these days

resently i've become busier than before,i am busy preparing my presentation and tests,as well as designing posters,singing practice blah blah blah.
i think i should be more concentrate on my studies,because i always waste my time doing something not that imperative,or distracting from other things,or my mind just blank out when i'm studying.
this semester our english class give us some tasks,i think its really tough to do all things well,i always delay my readings,and forget to prepare questions for the next class...i should examine myself this time...
