What do the credits mean?

Credits are assigned to regulated qualifications and recognised by universities in many countries. The credits you achieve through some qualifications may count towards others, if you have covered similar learning outcomes at a comparable level. As a general rule, ten hours of learning (including both taught and self-study) equates to approximately one credit. 

ABE's full RQF diplomas at Levels 4, 5 & 6 carry up to 120 credits each and this matches the stages of a degree.
