Might as well drop Physics A level?

Hey!

I'm currently a year 13 student, doing Maths & Physics A level, as well as a diploma (12 units) in Business Studies. I've achieved a grade C in Maths at AS, but planning to resit C2 & M1 alongside A2 Maths. I achieved a D* in my first 6 units, and predicted to achieve another D*. However, my other subject Physics is a bit of a problem, to be honest I've struggled especially through my first year, its the new OCR spec, and we did a mock AS examination at the end of year 12 and I got an E in the mock.

I've been to several open days, mainly interested in Reading/Leicester to study Economics. I've spoken to the lecturers and at the information points at the open days, and they've said If I get Distinction/Distinction/B in maths, I'll meet the entry requirements, regardless whether I do well or not in my physics.

My question is I feel like I should drop physics, so there's less stress going through on my mind and my solely focus can be on Maths, because I think I'm easily capable to get an A, and was disappointed to achieved a C, however has motivated me to get my head down throughout the whole year and study. However, If I do drop it I feel like I have wasted a year of my time on physics, if I'm going to get nothing from it.

My mind is currently 60% Dropping it, 30% Not dropping it and hoping for the best & 10% Not sure.

Any suggestions?

Thank you
