It should be the school where you go to do experiments. This experiment is either physics or chemistry. Schools should open laboratories to teach you to do experiments before exams. Actually, it's nothing. Our classmates haven't done experiments before, so it's almost enough to go there and see the people next to them do it once, and it's still full marks. Well, ABCDE and so on are all teachers who scare students and won't let them go. I took the college entrance examination this year, and my sister screamed with fear this year. What is the quality evaluation of the college entrance examination? Just a cloud. You can get an a by sucking up to the head teacher. This is the inferiority of education in China. There is nothing to worry about.
Well, my experience in the senior high school entrance examination experiment is to respect the invigilator, first of all, to say hello and so on. Generally, one teacher sees two students. I drew the one with two light bulbs physically. Nervousness is unacceptable. When I was nervous, I made a hundred mistakes. After landing, politely ask the teacher for the score, no matter how much, thank you. I asked for a perfect score of 15, and he told me that he gave me a score of 12, but he gave me a perfect score after the final score came out. . .
Improvise, mine is just a reference, it varies from place to place ~
I wish you full marks in the exam!
