I hope to apply to UCL for physics? Are these grades good enough:
Grades
Maths 8 Physics 8 Biology 7 Chemistry 7 French 6 English literature 7 English language 8 History 7 Business 5
My current A levels are maths, physics, chemistry and economics. If I get an A* in maths, and A* in physics, an A* in economics and an A in chemistry can i get in?
these are perfectly fine, chill mate. UCL is competitive but you have solid GCSEs, and it's your A-levels that really matter. If you get 3A*s and an A at A-level, you'll be a very strong applicant. I wouldn't stress.
