For Chemical Engineering Chemistry and Maths as your friend is probably aware are usually needed. I’ve checked the requirements for uk unis and this combination will get you into the vast vast majority of them. However a few of the top unis do require Maths, Chem and another related subject (Physics and FM are included).
Are they absolutely set on chemical engineering? I ask this because if there’s a chance they might switch to a different field of engineering then they will absolutely need Physics so if that’s the case I would recommend taking it.
Are they also certain you want to take 4 a levels? I know some schools mandate it and im not advising against it as such but some people dont consider how much extra time is taken up by this. Think of it like this: if you take 3 subjects then youll have maybe 5 hours of study periods per week and 15 hours of homework on average; so 10 hours of homework outside of school hours. If you take 4 subjects then youll have a near full timetable and 20 hours of homework; so 20 hours of homework outside of school hours- are they prepared to do this?
So basically:Take Chem and Maths
If they only want to take 3 and might switch field of engineering- take Physics
If they still want to take 4 and might switch field of engineering- take Physics and Latin (as long as they enjoy and are confident they will excel in Latin)
If they still want to take 4 and are certain you will not switch fields- tell them to take whichever 2 they think they will enjoy and do the best at and also which they feel they will be able to manage their time in effectively considering coursework and difficulty of content.
If they are completely unsure of what subjects to take other than basing it on what will be helpful for chemical engineering then a choice from physics, fm and dt is preferred.
Hope this helps your friend out a little, have a nice day
