You can go to the website of the Physics Experiment Center and send short messages to the two teachers, saying that you have staggered the experimental reports, or it may be better to contact the teachers yourself, because the teachers don't know when to go to the website of the Physics Experiment Center. . . . . . Or go to the teacher in person, but I am thinking that the teacher's preview reports are all signed. When correcting the experiment report, the teacher should find Bush's own signature or the experiment he is not responsible for and give it to another teacher.
