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?”

ChemEng contains huge amount of physics, so you won't escape from physics if you choose chemistry :)

Huh, I was under the impression it was mostly math and chemistry. Like mixing, diffusion, fluids, thermo, etc. where does the physics come in? Or are we counting fluid/thermo stuff as physics?

I'm great at any physics where my letters don't have hats on them!

Physicsl chemistry (full of physics, that's more physics than chemistry). Thermodynamic, it's almost all about physics too. To understand chemical engineering in general (how columns, adsorebers, pumps, heat exchangers etc. work), you have to study physics. If you want chemistry, you may become lab assistant (minimum wage salary and hard labour). All the rest chemists have to study physics anyway
