Do more questions...
Repeat this many times.
In this way, you don't have to think about things, and you shouldn't be too entangled in remembering things.
You can ask the teacher to list the knowledge points, and the experienced teacher can clearly say the probability and direction of each point, and then the strategy of each knowledge point can be done.
Personally, I don't recommend rote memorization, because it's uncomfortable, and it's very difficult to remember that when you encounter a problem, you can use this method.
In short, the memorization and practice of knowledge points cannot be disconnected.
It is not recommended to ask the sea now, but under the current system, the question sea is still the best tactic.

Look for those comprehensive books, I forgot the specific name. It seems to be called a complete knowledge of physical chemistry or something.

First, comprehensive analysis:
This is the knowledge content that relates to the motion and transformation of physical elements in electrical age, as well as the electron-positron and electron-electronic properties of the element.
Second, the metallicity is converted to oxidation and reduction
1. Oxidation and reducibility are general terms, which refer to the ability of matter and sparrow to gain and lose electrons.
2. Non-metallic and metallicity refer to the redox properties of the corresponding elemental elements of the elements.
3. If Cl is strong in non-metallic, it means that Cl has strong oxidation in Cl2. Let's not say that Cl2 is strong in non-metallic properties.
4. Non-metallic and metallic refer to the elements, oxidation and reduction are elemental, for the convenience of memory, non-metallic is oxidation, metallicity is reduction.
Explanation of physical terms:
1. Elemental metallicity: It indicates how easy it is for an element to lose electrons. The more susceptible an element is to lose electrons, the more metallic it is of the element.
Second, the non-metallic nature of the element: it indicates the difficulty of the element to obtain electrons. The easier it is for an element to get electrons, the stronger the non-metallic nature of the element.
3. Oxidation: It indicates the ease with which a substance can obtain electrons. The easier it is for a substance to get an electric abuser, the stronger the metallicity of the substance.
Fourth, reducibility: It indicates how easy it is for a substance to lose electrons. The more likely a substance is to lose electrons, the more non-metallic the substance is.

1. The concept should be clear 2. Mechanics, and we must learn force analysis well. This is the basis for solving all problems 3 Is a celestial body near-Earth or not, which formulas are true, note, **substitution, binary star problem, Kepler's third law 4 Newton's second law, third law 5 Motion of particles in an electric field 6 Circular motion 7 Flat throwing, quasi-flat throwing 8 Capacitance and resistance calculation 9 Circuit design, voltmeter ammeter internal and external connection 10 Home circuits 11 Transformers 12 Electromagnetic induction, ampere force, Lorenzi force, Ampere's rule, left-hand rule, right-hand rule 13History of physics (very important).
Take a look at three or two and solve it.
Compulsory 1 focuses on force, resultant force, component force, parallelogram law of force, three common types of force, three elements of force, time, moment, displacement, distance, speed, rate, instantaneous velocity, average velocity, average velocity, acceleration, and common-point force equilibrium (equilibrium condition).
Lens: An optical element made of a transparent substance (usually glass) with at least one surface that is part of a spherical surface and acts as a refractive element of light. >>>More
Work is also called mechanical work, which is a physical quantity in physics that represents the accumulation of space where the force acts on an object, and work is a scalar quantity, and its magnitude is equal to the scalar product of the force and the displacement of the point of action, and the SI unit is joules. >>>More
There are nine physics knowledge points
1. Gases, liquids and solids can all diffuse. The speed of diffusion is temperature dependent. The diffusion phenomenon shows that the molecules of all substances are in a never-ending irregular motion, and indirectly proves that there is a gap between the molecules. >>>More
