The teacher understands as soon as he says it, and is wrong as soon as he does it;
The teacher's questions are very simple for him, and he may feel very hard when he wants to do them himself;
Especially when making multiple-choice questions, it's luck to be uncertain which one to choose.
There is nothing wrong with the exam, and that's where the mistake lies.
Either there are missing symbols here or there is no classified discussion.
If the answer is often incomplete, the defendant's teacher will deduct points.
It's really a pity that you can write the wrong answer and deduct points for nothing.
Are you in the same situation? If you have the same points, you can do the following:
1, when doing multiple-choice questions, read all four answers of ABCD carefully and consider them comprehensively.
Then choose the most suitable option, and the general correct rate is relatively high;
2. When there are similar answers, see if there are brackets in the question. If there are instructions, you must follow them, otherwise it will not meet the requirements;
3. If there are many answers, we must discuss them in categories and divide them as thoroughly as possible;
4. When doing a good job, look back to see if it is correct, or if there is a simpler method;
When you encounter a problem, you can't find a solution to the problem for a while, and you don't have to do it. Let it cool down first
Reorganize the problem and find a breakthrough;
6. When encountering geometric figures, learn to draw; The combination of numbers and shapes is very important;
7. When encountering dynamic geometry problems, you should draw a sketch at any time according to the requirements of graphics;
8. When you really encounter a question and still have no idea after thinking about it for a long time, you can look at Baidu to see if anyone else has answered it (sometimes the answer on Baidu is wrong, but it is still adopted by many students), or ask the teacher with a question.
Well, that's what I'm talking about. I hope it helps you. I wish you progress!
