Employers really aren't interested in what school qualifications you have when they recieve your flying CV. The first thing they look is your hours. If these are not high enough for their 'requirements' your CV is filed in the B1N ASAP and if you're lucky a PFO mailed out. You are wasting their time listing all your GCSE, A-Level, BTEC's etc on your flying CV so in view of this you are not at a disadvantage at the application stage at all because I for one do not list acedemic quals on my flying CV.
If you speak to the recruiters they will tell you this.
