Career Advice How much Maths is in ChemEng?

Hii, im a year 12 student who is currently thinking about what course i should do. And im stuck between Maths and ChemEng. I only recently discovered a Maths course is just mainly proofs which isnt exactly what i was looking for. I absolutely love Maths and i really want to continue it in the future and I think the maths in engineering is my best bet as it is applied. But the thing is, i dont do physics so the engineering courses i could do are very limited. So i can really only apply for ChemEng.

My main question is “Is chemical engineering majority maths and roughly what percentage of the course is just maths?”

A lot of chemical engineering, especially process eng stuff is based on maths, and depending on what kind of topics you're into you can really lean heavily into maths later on in your course. You might find anywhere from 20-50% maths according to your module choices. Process and thermo modelling is very maths heavy, and there's a lot of scope for research into new mathematical models if that's what you're into. There's definitely enough maths to sink your teeth into even in an applied context. I'd say go for it!

Naa Not so much in undergraduate

it depends on your modules tho, my uni has a few modelling modules which are almost entirely transforming mathematical models to apply them to different use cases and I'm doing a summer project in process modelling right now which uses a lot of calculus type maths. It's obvs all engineering at the end of the day but the emphasis is on making the maths useful
