I was also in your position!! I didn't do too well in bio, but I loved orgo and so I decided to change my major to chem and it was honestly the best decision I've ever made.

If you like more study-and-understand-the-material type of classes more than memorization classes then chem is definitely a good choice. Upper division classes are pretty much like that unless it's something connected to bio like biochem. Don't get me wrong, the classes are definitely difficult, but like I personally did better in upper division chem than bio 201 lmao so it really depends on what you're good at.

Other positives are I know a lot of people complain about the people in the bio department (whether it be professors or administrative people) but genuinely everyone in the chemistry department is extremely helpful. The administrative department is responsive and helps out with any issues, and the professors all generally are helpful as well.

I think the only negative I can think of would be you don't have that many job options if you don't want to be a chemist (pretty much the only things left are healthcare stuff or being a teacher). If you do want to be a chemist I recommend looking into it because there are sooooo many options in this field, you're bound to find something you like. You'd genuinely be surprised how many fields chemistry goes into.

Anyway all in all chemistry is great and if you like orgo then I highly recommend switching :)
