Chemical engineering- A Level Options?

I'm in year 11 currently, gonna do gcses this year, I've been maintaining 8's and 9s in the sciences, maths, eng, my option subjects and hopefully real gcses too. I'm interested in chemical engineering, but confused about my third A level option. I know ill have to do Maths and Chem, but I feel like Physics as the third may be hard-especially because I'm not astonishingly good at Maths even though I manage to scrape an 8. I really like Psychology, but would that close doors? I'm neutral about Biology, would it be easier than Physics though?

HI! I’m a year 13 student currently studying a level maths, physics and chemistry, and just sent off my UCAS application to study chemical engineering.

In year 12, I did Spanish as my 3rd choice but then decided to swap to physics at the beginning of my 2nd term. This is why..

Researching, the average chemical engineering course consists of about 70% maths and physics, and 30% chemistry (along those lines). So.. being reluctant to pick physics because you’re not very ‘good’ at maths is a temporary solution - you’ll do a lot of applied maths and physics at uni. Especially in your first year, as they normally use this year to recap everything of relevance that was taught during a levels.

Now, some might say that doing the ‘norm’ a level combination would make your application stronger.
I’m not too sure about this, having the right grades and a strong personal statement should be enough for a consideration. Yet, I don’t know anyone who has in fact applied to this course and didn’t do maths, physics and chem.

However, when you look at subject and entry requirements on universities’ websites, they do accept applicants who didn’t study physics. (Accept: maths and either chemistry or physics or sometimes a different science). The only universities I’ve come across that explicitly ask for physics are oxbridge and Imperial.

In summary, there’s no right or wrong answer.
Unless you’re thinking of applying to oxbridge or imperial, choosing a 3rd option that’s isn’t physics would close your doors.

If you do decide that your 3rd option wont be physics, make sure that in your personal statement you showcase your Mathematical and problem solving skills through extra supracurriculars. For example, participate in the UKMT challenge, maths and chemistry Olympiad, CGHQ’s puzzles, etc.

In terms of Biology, it is considered to be on the easier end of the spectrum in terms of a levels, you’ll obviously still need to put in a lot of hard work thought.

Also!! Don’t be discouraged in choosing physics just because you’re ’not very good’ at maths. I achieved an 8 in GCSE math & 7 in physics and I’m now predicted A* in both. Nonetheless, I did find physics very challenging in year 12 and had to put in a lot of work to get to my desired grade.

If you want any advice on how I achieved those grades do let me know, I’d be more than happy to help! I’ve also got friends who do exceptionally well in biology and psychology who are open to sharing studying tips if you do decide to pick those subjects.

Good Luck! :biggrin:

I think something to keep in mind is that chemical engineering is more maths and physics than chemistry. While often chemistry is required at A-level, you usually don't do much more than that in the degree itself.

If you don't like and/or struggle with physics and maths then chemical engineering may not be the best option anyway.

Whats drawing you to chemical engineering? As others have said it’s a very maths and physics based course so i would suggest you look at other options if you aren’t a big maths and physics fan. Chem and psych are great options to have for stem, id also suggest adding a third core science (maths, physics or bio) based on what interests you more to keep options open but if none of those really appeal then choose something else. Social sciences sit well with psych as well 🙂 Also if getting an 8 is a lot of work for you in maths then seriously consider if maths is a viable option for you ability-wise, the first half term of a level will be getting you up to a grade 8 or 9 standard and then youre straight into harder content quite quickly.

i really like chem, i think its a flexible field and theres different specialisations- R&D, water treatment, sustainability- i find all those interesting. I do like physics and math but theyre just not something im as passionate about. l also dont suck at math but i was just wondering whether its ok to take if you arent like amazingly good at it. Tysm for your help, i definitely will evaluate social sciences and psych, as well as if maths would be good for me

I would just say if your main interest is in chemistry there's not really any degree that covers a substantial amount if chemistry except chemistry itself :redface:

There's a lot you can do with a chemistry degree though so if that's your main interest maybe focus in on that :biggrin:

I’ve applied to Imperial, Bath, UCL, Leeds and Sheffield. Apart from getting offered an interview with Imperial, i’m still waiting on the other unis


That is cool...did you sit the esat in january?

Thank you so much for your reply, it's genuinely so helpful.
I was aware that physics would be involved, and I actually do enjoy it- I just don't think I'm as passionate about it, but I could definitely put up with it. About the A-level combo, most universities, if not all, that I have researched about do not require BOTH Chemistry and Physics, yet like you say...there are rarely applicants who go in other directions- is that because they feel like they'll be most prepared for engineering with that monstrosity of a combo? Who knows😭

I'm probably, or rather certainly, not interested in oxbridge so I think I'll be safe lol, though I definitely will weigh up both Biology and Physics options, as well as basing them off of how well I do in gcses. However, our school is making us do early A-level choices right after mock results which are in a weeks time 💔 hence the stress. I appreciate the advice about the Math competitions, I think they'll be useful and I will try to apply.

Thank you so much for the encouragement, your grades seem great, predicted A* is amazing! There's just so much competition so I'm worried if I'm not the best of the best then there's no point? I'm aware that's an illogical way of thinking so I'm trying to change that...also yesss pls share tips for your A level subjects, do you feel like they were much more challenging than GCSE's, what study methods did you use?

Thanks again, I appreciate this so much!!!

I know its a bit of a later reply, but as a current chemical engineering student I did maths, further maths and chemistry as my A-levels. As someone who didn't do physics at a-level, I find the physics content in the course fine, and feel as if not taking physics at a-level hasn't restricted me.

I do agree with others on this that chemical engineering is very maths heavy and doesn't involve a lot of chemistry, I had two modules that were chemistry based in my first year and for the rest of them it had some chemistry dotted in but not loads.

There was a couple of people in my course who also chose subjects such as biology instead of physics and they don't feel as if its affected them as much either. As in our first year we learnt the concepts from scratch, (such as definitions, resistance calculations, ect) so we would all be in the same spot. I'm not sure if this is the same for every university but its how mine worked.

Overall, I think that not taking physics at A-level would not impact you massively, but you do have to be prepared to ask any lecturers if you don't understand any concepts. Just be aware that this course does involve a lot maths, especially the physics based modules, although once you understand the concepts and methods its mostly okay.
