(1) In junior high school, chemistry is the easiest thing to improve. You can take a short and intensive review method:
First of all, make a general plan according to your current foundation and learning situation. For example, if your pH is particularly weak, then you have to start with the textbook, read the textbook first, and then do the problem accordingly. If you do the problem, you must have a detailed answer. It's a waste of time to do it yourself first, and then make a wrong answer or make it unclear. After doing a lot of questions, give yourself a test. This process is a process of "learning core knowledge-knowledge application and mastery-self-detection and improvement". Need to pay attention to the setting of the length of time, such as the chapter on acid, alkali and salt, basically once a week. Of course, junior high school chemistry is a comprehensive chapter. You have laid a solid foundation in this chapter, which is also helpful for learning other chapters.
(2) The big head is mathematics, but there are too many contents. Even after reading the basic knowledge, it takes a lot of time for each knowledge point to do a problem. As the entrance examination approaches, you are not allowed to adopt this slow and steady method. Now basic schools will begin to issue comprehensive review papers or special review papers. It is more difficult to review the topic of the special paper, and the intermediate questions must be understood. If it is difficult or difficult, just give up. Cherish every opportunity to make a comprehensive volume (simulation volume). When I say cherish, I mean: you should attach great importance to every trial lecture, understand 90% of the whole article every time, and do the questions-answer analysis-to ensure that you can do the same kind of questions well. After this process, you are cherishing time, not wasting it.
(3) physics, 70 points can get 50 points, the best of these three subjects. It is suggested that according to the review method of mathematics, we should try our best to learn in one style, which will definitely improve.
In addition, the mentality should be stable and not rushed, so as to maintain efficient review! Have confidence, as long as you grasp it well for the last time, you will definitely get a higher grade in the senior high school entrance examination.
