How to learn high school math and physics, how to learn high school math and physics?

I feel that in order to learn high school math well, you generally need three aspects.

1: Listen carefully in class (although there are negative exceptions, but after all, there are few).

2: Be good at summarizing knowledge points after class.

3: Do as many practice questions as possible, but don't do it blindly, you must grasp the typical and key high schools, after all, the time is much tighter, and at the same time, you must integrate and pay attention to mathematical ideas and methods.

As for physics, I think there are four aspects.

The first 3 aspects are similar to learning mathematics, the 4th aspect is to insist on independent thinking, good at analyzing problems, and I firmly believe that this is the key to learning physics Sometimes as long as you think about a class of problems thoroughly, the same kind of problems will not deviate from their origins no matter how they change, and the rest is the problem of mathematical calculation... But if you want to really learn physics well, you must not just learn to do problems, but also learn the way of thinking about problems, and I think this is a step further.

Hope the above can be helpful to you!!

If you don't listen to class, no matter how hard you try, it's absolutely useless This is my chemistry experience As for physics, I've always memorized the little knowledge points that should be memorized, and the rest of the calculation problems are just like math and physics, more.

The relationship between problem review and problem solving.

Some candidates do not pay enough attention to the examination of the question, and rush to write at a hurry, so that the conditions and requirements of the question are not thoroughly understood, and it is impossible to talk about how to dig out the implicit conditions from the question and inspire the idea of solving the problem, so there are naturally many mistakes in solving the problem. Only by patiently and carefully reviewing the questions and accurately grasping the key words and quantities in the questions (such as"At least"，"a＞0", the range of values of independent variables, etc.), and get as much information as possible from them, so as to quickly find the direction of solving the problem.

Will do"with"Scoring"relationship.

To convert your problem-solving strategy into scoring points, you mainly rely on accurate and complete mathematical language expression, which is often overlooked by some test takers, so it appears in large numbers on the paper"Yes and no""Yes but not quite", the candidate's own assessment score is far from the actual score. As in the solid geometry argument"Skip a step", so that many people lose 1 3 or more scores, algebraic arguments"Illustrations to prove", although the idea of solving the problem is correct or even very ingenious, but because it is not good at putting"Graphical language"Accurately translated"Written language", the score is pitiful; Another example is last year's 17 questions of trigonometric function image transformation, many candidates"Know what to expect"But it is not clear, and there are not a few people who deduct points. Only pay attention to the language of the problem-solving process"Will do"The question talent"Scoring"。

The relationship between fast and accurate.

In the current situation of large number of questions and tight time"Accurate"Words are especially important. Only"Accurate"to score, only"Accurate"You don't have to think about spending any more time checking it"Fast"It is the result of ordinary training, not a problem that can be solved in the examination room. For example, in last year's application question 21, it is not difficult to list the analytical formula of the piecewise function, but a considerable number of candidates miscalculate the quadratic function or even the primary function in a hurry, and although the subsequent part of the problem solving idea is correct and takes time to calculate, it is almost impossible to get points, which is inconsistent with the actual level of the candidates.

Appropriately slow and accurate, you can score a little more; On the contrary, hurry up, make a mistake, and spend time and still don't get points.

The relationship between difficult and easy questions.

After getting the test paper, you should read through the whole paper, and generally speaking, you should answer in the order of easy and then difficult, simple and then complex. In recent years, the order of the exam questions is not exactly the order of difficulty, for example, last year's 19 questions were more difficult than 20 and 21, so when answering the questions, you should arrange your time reasonably and do not type on a stuck question"Protracted war", which is time-consuming and does not get points, and the questions that can be done are delayed. In recent years, the math test questions have been removed"A check"Turn to"Multi-question checks", so the answers are set up in a hierarchical manner"Steps", the entrance is wide, it is easy to start, but it is difficult to go deeper, and it is difficult to solve it in the end, so there will be seemingly easy questions"Biting the hand"There are also points to be scored for seemingly difficult questions.

So see in the exam"Easy"The question should not be taken lightly and see new faces"Difficult"Don't be timid about the questions, think calmly and analyze carefully, and you will definitely get the marks you deserve. I hope you will try to use the method just described. I'll be happy if it works.
