Judging from the biology over the years, about 60% of the examination contents are about basic knowledge, basic skills and basic knowledge application ability. To ensure that 60% of the basic scores can be scored at a high rate, it is necessary to read the textbooks carefully and master the knowledge of the textbooks. In the review stage, it is very dangerous to focus on the topic instead of the textbook and covet one or two exams or simulate the leap in the quality of the exam.

We should take notes on similar and confusing knowledge points or closely related knowledge points in each chapter, and classify, compare and summarize them.

2 Understand charts and improve your ability.

The score of biological chart questions is large, and the chart questions are more and more complex and comprehensive, showing the phenomenon that one question has multiple charts (tables), and charts and curves are integrated into one. So we should pay attention to textbooks or charts and curves closely related to textbooks. It is necessary to read, recognize and analyze pictures, strengthen the sense of image, and further raise perceptual knowledge to rational knowledge.

Attach importance to experimental operation and cultivate basic skills and innovative ability

The scoring rate of biological experiment questions over the years is low. The reason for the low score rate is that there is no actual operation experiment or no real understanding of the principle and method of the experiment. After the experiment, there was no process of returning 100 million yuan and no analysis results.

4 read the catalogue and grasp the whole.

The catalogue is the epitome and outline of the whole book, and reading the catalogue helps students to master the knowledge system of the whole book.

5 Do exercises well, and draw inferences from others.

Do after-school exercises in textbooks, previous tests, etc. After doing the exercises, sum up the knowledge points and problem-solving methods, and draw inferences to sublimate the knowledge. When doing problems, you can't abandon the foundation and do some difficult, biased and strange problems. This is even more calm and clear.

By implementing the above five points and balancing and coordinating their relations, we can get twice the result with half the effort and achieve satisfactory results in review.
