To answer your question first, I am a bioengineering major, and the requirements for mathematics in the university are very low. You don't have to worry about that. If you are not good at math, it is really good to consider this aspect.

But by the way, you should consider your actual situation clearly. The employment rate of biology major is not very good. I'm so worried about this problem now that I'm at a loss. Unless you really like this major and want to make a breakthrough in this field, I suggest you think it over carefully and make a comprehensive analysis before you act.
