As the saying goes, interest is the best teacher. You are not good at these two sciences largely because you don't like them psychologically. You must find a way to like them or at least not hate them.
Chemistry has a lot to be strengthened. You can buy a well-organized teaching aid and insist on strengthening your memory from scratch for a period of time, and you will find that it is not that difficult.
Biology is a subject that is difficult to get high marks. There is a slogan in the college entrance examination: those who get comprehensive management get the world.
There is also a saying: those who get biology have to be treated comprehensively.
What makes you say that? /How can it be?
This is the conclusion drawn through sorting out and counting the scores of candidates' college entrance examination for many years.
Science scores 300 points. Can you not win the 290-point college entrance examination?
Of the three clans, biology is the most difficult to distinguish.
Biology: It requires not only mathematical and physical thinking, but also rigor and diligence in Chinese and English. No one dared to say that I knew biology before the exam, so I had to take a sub-exam.
Dare to say yes
The key to learning biology well: 1. Read through the textbook.
2. Deep and meticulous understanding of knowledge points
3. Pay attention to the illustrations in the teaching materials (all are key points)
4. Brush the questions to analyze the correct answers and remember them.
Finally, I wish you find a suitable learning method, overcome difficulties and succeed in your studies.
