Hi I applied to Bristol and Southampton for Aerospace for a 2023 start. I took Maths, Physics, Chemistry and a level 3 EPQ, predicted A* in each. I got offers for both unis. My advice would just be to get those top predicted grades and have a good personal statement. I think Bath is be a similar story, but i’m aware that you need entrance exams (and possibly an interview) for Imperial. Further Maths would definitely help there. Good luck with your application!
