As a Bio Natsci I actually found Chemistry quite a refreshing change from the biology course. This is because with a lot of the biology options there is emphasis on reading around the course, whereas for Chemistry there is a set amount of work to do but once it’s done there is no need to do any additional work.

I have also found that first year chemistry has helped a lot in part 1B Biochemistry, so if you intend to take this option I would definitely recommend Chemistry.
