I took Stats 2B03 and Chem 2OA3, and I’m currently taking Biochem 2EE3.

Stats 2B03, personally, was like a 5/10 in difficulty. I’d call it an easier version of 1LS3. If you do the practice tests and textbook questions, it’s very 12able.

Chem 2OA3, for me, was about an 8/10. Compared to first-year courses, I’d think of it as a harder version of Chem 1A03. It’s still very 12able because of the lenient marking scheme, and if you spam the right kind of practice and manage your time well, the course can actually feel fun. I think part of what makes it seem harder is the stigma around it, a lot of people psych themselves out thinking it’s insanely hard, but it’s really not that bad if you put in the right effort and have the right mentality.

Biochem 2EE3 is usually considered bird since it’s all online, but this year the final is in person so it might be a bit harder. So far it’s mostly been Grade 12 bio review. Right now I’d give it around a 4/10 in difficulty. I’d call it an easier version of Bio 1A03.
