How to learn science well and lay a good foundation?

I'm a senior high-level one. You didn't study hard in your first year of high school. Honestly, I'm the same.

The high one is a mess, and the creatures are not on 28

But in the second year of high school, I studied hard and felt that it was very casual. The main thing is interest and understanding.

If you are interested in any subject, study hard, and throw the liberal arts in the garbage heap. Mathematics must be clear, otherwise the calculation problems of chemistry, biophysics will be a headache. Secondly, don't ask the teacher if you don't know.

All questions are not asked about speed. Don't worry about anything, the teacher will tell you. Everything must be understood, even if everyone understands, if you don't understand, you have to ask the teacher if you feel faceless.

Buy a few workbooks that explain the depth of the lessons. Do it.

Physical electrical grabbing. The idea of chemical equilibrium... I don't just read the old books. Look up information on the Internet.

First of all, you must have the confidence to correct bad study habits and be determined yourself, otherwise everything is not to be talked about, pay attention to diet and rest.

Science should grasp the key and core knowledge points Because part of the first year of high school is basic and there are many connections with what you learn later, so the foundation is not straightened out, and it is difficult to study later I suggest that you find a teacher to help you straighten it out (let your parents spend some money to go to the teacher's house and let him help you straighten it out) The main thing is to straighten out the relationship Those are the priority tutoring that directly affects your current lectures and grades Other scattered chapter knowledge points Look back on yourself and strive to keep up with the progress of a subject in the shortest possible time I personally think that as long as you really want to learn You can see results in a short period of time A subject is clear You will have self-confidence If you have other questions, you will ask them with questions The main thing is to ask yourself more and think more Learning is a process of persistence and accumulation As long as you keep working hard and really change yourself, you will definitely succeed I didn't have a good foundation back then, but then I summarized and sorted out the 3 major books of the question types that I couldn't let the teacher tell me all day long Classmates also asked Cram School The effect is still obvious Once you really enter the state of having to learn Everything else can be abandoned And it's very rewarding I learned every question and gave me a lot of encouragement In the end, my grades improved by 80 points Now I am in medical school Think about it if I gave up at that time I really don't know that I am now in ** mixing.

Physics: The summary is the most important, including the summary of the classroom teacher, the summary of the self-preview review after class, the summary of the wrong questions, it is best to find a book, record the experience, usually turn over more, for the formula, the memory also needs to be understood, according to the specific situation appropriate use, pay attention to the scope of application of the formula.

Don't equate physics with mathematics, and develop a good habit of writing for special calculation problems.

For most problems, the diagram is quite important, the key to the electrical circuit diagram is to simplify, we can distinguish the connection situation at a glance, the force analysis of mechanics is the basis of the problem, the optical path diagram can help us analyze the problem, and even the boiling evaporation of heat will use the diagram.

Of course, it's easier said than done, but don't be pressured, I think the key to physics is to get started, and touch will be bypassed.

Practice a lot, do a lot of practice, physics is very interesting Chemistry: The basis of chemistry is nothing more than elements and chemical reactions, I think you should first have a good grasp of the principle of chemical reactions, and know what chemical reactions are.

The steps are as follows:

1. Have a deep understanding of what a chemical reaction is and what are the main components of a chemical reaction.

2. To learn redox reaction, you must know what is oxidation reaction and what is reduction reaction.

3. Memorize and memorize commonly used chemical reaction equations and typical chemical reaction equations.

4. Read the texts carefully to enhance your interest in chemistry.

5. Enhance extracurricular exercises, and it is recommended to choose some exercises with low difficulty to enhance your confidence.
