The following suggestions are for reference: 1. Never memorize mathematics and physics, including formulas, definitions, theorems and laws. A profound and accurate understanding is the most important; 2. There is an invisible "scientific thought" in science represented by mathematics, which is the soul of mathematics and physics, that is, thinking activities marked by analysis, synthesis and reasoning; In learning, we should always pay attention to understand it and grasp it; 3. Under the premise of resolutely opposing "crowd tactics", emphasize doing a certain amount of exercises; 4. Be prepared: the more you learn later, the more abstract, the more flexible and interesting you will be; 5, mathematics, physics knowledge from the beginning, every bit can not be missed; If there is any omission, it should be made up in time; 6. Physics is close to mathematics, and the method is similar to mathematics; 7. Although chemistry is a science subject, it has always been called a "minor liberal arts subject". The content of reasoning is far less than mathematics and physics, while the content of memory is like liberal arts; Refer to the basic methods of liberal arts to learn chemistry; 8. Don't be afraid of knowledge barriers (such as encountering difficulties). ). The real kung fu of mathematics and physics is practiced in front of obstacles; Believe in yourself, start from the simplest and most basic place (also the most important place), don't worry, you will certainly gain something.
