So initially I picked geo bc I thought it's much easier than biology and there's higher chance on representing school on competitions bc there are not many students taking the class. I'd like to take both classes too if I'm allowed. I just can't stop thinking about it bc I'm afraid that biology is not an easy subject and taking the class would help prepare uni entrance a lot but I took other subject instead bc for this time my focus is being active participating in competition. Can I know how much part of biology comprises geo? I'm a hs freshman btw, thanks for the reply!
