Ring the bell and start to do the first question, which is relatively smooth until the volume is compared (the line and surface are a little difficult to calculate, and it takes a little time). Then I couldn't write the paper, jumped, and couldn't write twelve questions. At the beginning of the fill-in-the-blank question, I began to sweat so much that I was so nervous that I almost didn't read it correctly for the first time. But I simply wrote the first two empty words, and the third empty thought for a long time before I thought of the idea, and I don't know if it was right. Anyway, whenever I have an idea, I regard it as my lifeline. Fourth, I want to try knowing that I can't write it, and my mentality has collapsed directly.
Results the series was miscalculated, and the results were different after several calculations. So I decided to jump, 18. The question may be too tense. I've been thinking about it for a long time. Fortunately, I figured it out, but time is running out. 19.22 smooth. 20.2 1 only wrote the first space and didn't have time to read the second space. Turn around and look at the questions you didn't write before. Then at this time, a piece of draft paper is simply not enough! I applied for draft paper, but I didn't know that the original draft paper should be collected (there are many keys to solving problems), so I didn't want draft paper. Then the draft paper was dense and flustered, and nothing was written in the last ten minutes.
The past is over, although the school I want to go to is probably missed, but I will try my best to live up to the hard work of this year.
Generally speaking, this volume examines the students' ability to resist pressure and calculate, with a high degree. 19 put the r formula of correlation coefficient below (although it is useless at all). Derivative is a refreshing practical experience in the form of routine questions, which shows that the level of the questioner is comparable to that of Wei Dongyi.
The difficulty of multiple-choice questions and fill-in-the-blank questions is moderate, which greatly tests the answering ability of candidates and also contains extremely high scientific knowledge (such as Chang 'e aircraft). Generally speaking, the writing level of volume B is extremely high, and at the same time it gives students a sense of intimacy. If they try, they will die. I hope the questioner can see this answer and tell her home address privately. I will personally thank you!
