Biomedical Engineering Jordanstown

Not sure if this is the write place to post this, but I applied to University last year and got 4 of 4 offers and then was offered a Higher Level Apprenticeship for a local company in electronic and electrical engineering specifically Automation working 4 days a week and a 12 hour study day for the 5th day. This will get me a foundation degree at the end of 3 years for free however I'm not learning anything at all in my job and basically confined to office work which has no learning and is monotonous. I was thinking of leaving and going to Uni as they have a place for me if I want it for Biomedical Engineering which was my original first choice, just scared of the move and making sure it would be the right decision, anyone offer any advice on the course, I'm now 22 and don't want to waste anymore time deciding my educational future, any and all help appreciated and apologies for the long post.
