hi there! i'm in year 13 at the moment, and i'm doing Biology, Chemistry and Physics. i've just applied for university to do Pharmacology, and i'm predicted A*AB (A* in chem, A in bio, B in phys)
now, before i say what i'm going to say, i'd just like to disclaim that i'm not trying to put you off physics, because ultimately it's your decision. i can see a lot of people above me have said similar things, but i'd like to say it coming from someone who has actually done those 3 options.
taking physics A level was the worst decision i have ever made. when i started A levels, i was doing the 3 sciences, and psychology. after 6 weeks we were all told to drop one, so i dropped psychology. at the time, psychology was my best subject, but i found it boring and long, and i didn't like doing the essays, even though i got full marks on them. so, even though it was my lowest grade, i chose to take physics. both my teachers assured me that taking physics without maths would be fine, and that i'd "get it eventually." i got a 9 in GCSE physics, and an 8 in GCSE maths, so it wasn't at all like i was bad at maths or physics before A level.
quickly, it became evident that everyone else in my class - all of whom took maths - were much better than me. period. their maths skills were much more advanced and refined, meanwhile i was struggling to relearn concepts i'd learnt at GCSE.
additionally, the trouble with A level physics is that, if you don't understand one bit of the topic, you don't understand any of the topic. everything links together, and unfortunately, almost everything is also supported by the maths.
halfway through year 12, i started losing hope, because everyone else was so much better than me, and i wasn't getting it. i'd gotten nothing much higher than a D in my assessments, but my friends and teachers just kept saying "you'll get it eventually!"
i believed them, so despite the fact i was losing hope, i kept going. i stayed after school, i asked for help all the time, i got other friends to help, i did extra practice questions. and it got me nowhere. at the end of year 12, i managed to scrape a C, but then i quickly fell back down to a D once we started doing A2 content.
now i'm in year 13, and things are still not going great. and i all i can really say is that, if someone had truthfully told me how hard A level physics was, last year, i would not have taken it. in my most recent paper 1 practices, i've gotten 2 Ds and a U. there's content we studied at the start of year 12, at the very start of the course, which even now - after a year - i'm still getting wrong. in the mock (i did it 4 days ago yikes) i'd be surprised if i got more than an E.
and now, i'm stuck in this situation where unis need me to get AAB, and i'm not sure if i can get a B, and i hate to think that i might wake up on results day next year, look at UCAS, and it says i haven't gotten into my choices.
overall, i can't recommend taking physics without maths. i absolutely regret the decision. if you're applying to medicine, biology and chemistry are the only subjects you need, however universities tend to prefer you if you have another related subject. that's not to say you HAVE to have one, but either maths or maybe psychology could be a good call
