If your choosing out of the two of them definitely choose Maths as Physics is a very maths intense subject so demands a lot of the skills and knowledge you gain in doing A-Level Maths. If you do choose to do Physics perhaps at least do AS Maths on top.
Doing an A-Level either Physics or Maths gives you a lot of logical thinking skills and so both open up a wide variety of career paths.
Physics mainly opens up routes such as:
- Going into the many different types of Engineering
- Other Maths related fields or a degree in Physics
- Medicine/BioMed as these courses require 2 sciences (and sometimes maths)
Maths career opportunities:
- A degree in Maths is seen to be the most employable subjects to a variety of different skills since many different fields require Maths.
- Medicine if you have chosen to do 2 sciences.
- Economics, Accounting, Actuarial Sciences.
- Engineering (although most Engineering courses highly recommend you having Physics)
So, in summary, would choose Maths as it opens up more career as paths and because doing Physics means you'll need Maths Knowledge so if it's a one or the other situation and you are not able to choose both, go for Maths
