UCL Chemistry year 2 and 3

(urgent)
how difficult is year 2 and 3 for UCL Chemistry? I found year 1 really difficult to understand and get my head around the concepts. I am worried I won't manage in year 2, especially because Chemistry is not something I love, I am just doing it for a STEM degree.

so essentially I just want to know: is year 2 or 3 WAYYY more difficult than year 1?

Why are you "just doing it for a STEM degree"? What's the STEM degree for?
Also tagging @CheeseIsVeg to offer some advice about what you can expect to come in a Y2 & 3 of a Chem course at uni (not UCL).

Well, a STEM degree is generally better for career prospects as it leaves you open with more doors, also I was kind of pushed into university by my parents, and they insisted on me doing a "good degree" and in their eyes that is a STEM degree...but anyway that isin't the point anymore because I can't go back in time, I just need to figure out what to do going foward now, but I don't know if I should drop out and reapply for a course I would actually like.
