The next semester of senior three is here. If I didn't learn well last semester, it was really a bit troublesome, but as far as my experience is concerned, math in Grade One is poor, but Grade Two often gets about 100, so don't miss it, there is still time, do more problems, but the most important thing is to listen carefully in class. My tutor said that there is no pen and paper to attend class, but there must be no ears and eyes.
