Don’t reject your own application.
Apprenticeships are a lot more lenient on acceptable grades.
Apply for what interests you and see what you get back.
As for changing careers/employers, the degree you study as part of your apprenticeship would set you up for the same opportunities as any full time student studying the same degree. The only difference is you’d have far more work experience and proven competence, likely being able to skip having to do a graduate scheme.
