Comparison between history and biology;
If history is not particularly bad at ordinary times, has a little foundation, and doesn't particularly hate history, you can consider choosing history, but now history is generally closed, and it is not easy to remember many paragraphs in most exams.
Biology, as long as you are not ignorant at ordinary times and have a certain knowledge reserve, the senior high school entrance examination is relatively easy to deal with, and I believe most people are not very strong on those individual issues.
On the whole, what do you think if the junior high school biology exam is not strong? You can choose biology.
But if the intensity is not general, then choose history.
