Just after reading a real change function, my heart was relatively depressed, I came over and complained. I have been three years in my University. Every year, the mood of the exam is often connected with the Chinese New Year. The test is not good. The Malaysi Tiger is also, if you hang a few doors, you will not be very good this year, so you must cheer, put the remaining number of questions: 6 (Friday), real change (next Monday), partial differentiation ( Next Friday), TOEFL (next Saturday), count (next Tuesday). Depressed mood, helpless choice.
