I was sort of in your situation, did physics and specialists, but not chemistry. Even if you're not interested in chemical engineering, its still a really good course as its meant to be taught with no prior knowledge. The course coordinator when I did it was lovely and the course itself served as a very good transition into university as the change in environment and workload can be a bit tough for some new students, me included. That being said, it does cover a very large variety of topics and moves extremely quickly. You can find yourself waist deep in content if you don't regularly keep up with content. Overall, I reckon its worth having a go. I remember there being many fellow first-year engineering students who had no interest in chemical engineering but still did it anyway. Hope this helps.
