writing traning

Today,I woke up at 8 o'clock.
I ate cornflakes as breakfast.And I studied Math about 2 hours.
The reason that I study Math and English is to enter the graduatedschool.
Last august,I and my friend took examination to enter the graduatedschool.
But I failed in exam and my friend sucseeded.
I was sad but now,I recovered and study for next exam.

The English test is based on TOEFL,then I study English for TOEFL.
I will take the TOEFL exam next sunday,but I don't have confidence.
