I recommend a set of books that I have done in senior three, called "Challenge the Physics Finale of College Entrance Examination", which is divided into three volumes. First make the simplest orange one. If the title of that book is difficult to do, let's not consider the ending for the time being. Then make the yellow one. It may be a little difficult at first. Do a few typical examples, understand the answers, touch the routines, and it will be easy to do later.
I specifically searched the questions of Jiangsu 15 and 16. The last problem of mass spectrometer is to take the middle particle and move it up to the side until the original leftmost particle enters the right 1/3 area. As for the problem of electric field and magnetic field, draw it with a compass ruler and it will come out.
Do the physics finale problem
The first is proficiency, which routine should be used when you see a quick response to a question.
Second, the mentality should be stable. For those students who have the ability to do it but are unstable, they must do it with the mentality of "I can't do the last question" during the exam, and don't cram for it. Generally speaking, the result of cramming is that they made a mistake in the finale and didn't care to check the others.
Third, don't be afraid, don't be afraid that the middle process is complicated, don't be afraid that the final result is complicated, and don't be afraid of the finale itself. The intermediate process is complex, and the final result is likely to be concise; It doesn't matter if the result is complicated. It is very likely that the result is already complicated, and the uncomplicated one is called the grand finale. The physical finale is actually a paper tiger. It is not difficult to get rid of the feeling that the physical finale is difficult. It's not hard to think about it. People like me who haven't touched the high exam for three years can still do it. Regardless of mentality, active high school students should be better than me.
Personally, I think that it is unnecessary for others to participate too much in the finale of counseling. Let the parties do it themselves, look at the answers themselves, think for themselves, and click on what they really don't understand.
