Does junior high school biology need to brush the questions?

You don't need to brush the questions, nor do other subjects. The questions can never be finished, you can brush the original questions without delusion. But proper practice is still necessary.

It is recommended to draw a mind map. Living things can be divided into people, plants and animals. Geographical printing map of China to understand abbreviations, municipalities, famous geographical things, local climate, transportation, etc. Don't write too many words, just understand.

There will be unexpected problems, but generally there will be long materials. Read the materials and pictures carefully, and the answer is inside.

There are two choices for multiple-choice questions. If you feel fuzzy, choose according to climate and terrain habits. If you want to get 90 points out of 100, you can only make four mistakes in choosing geography, at most three. I wish you good grades in the exam.
