What is Business First Diploma A-levels like, are they hard-easy, etc..?

[G?G?'? L???l? M??????]

l am redoing my GCSE Maths and English, and my Business Studies Diploma A-levels in September and l was wondering how hard Business A-levels actually is? l got a G in my GCSE Business Studies due to the fact that l never revised enough but l am willing to change.

Thanks.
