Question about how study for College Entrance Examination
I am a third year repetition students,learning foundation very bad,but confidence and will learn,how can I in the year rapidly improved results?
Thank you for your encouragement!But now I am confused,I am very diligent review of the homework can have greater progress in the college entrance examination?Because my goal is admitted to a good university!Therefore,I hope that we can provide a learning method for base poor academic performance of students,such as me!

If your level is very poor,I advise you to review the language points one after another,for example,you can spend one day on reviewing the present tense.do some ralative exercises,and so on.There are not too much tenses in English.Day after day,I believe you will find you are improving.
Wish you succeed!
