Career
You need to be sure that you are not cutting off the option of work you may want to follow later if it requires a specific degree. As long as you have considered this fully, then a less academic route may be just the right thing for you.
There are still many career areas in which you can progress through working to gain the relevant professional qualifications without university study.
Generally speaking, employers are interested in why applicants have behaved in a certain way and what you have learned from the experience. You may find it useful to meet up with a Careers Counsellor to discuss how you will present this to an employer in a positive light.
You will have gained many transferable skills whilst being at university which you can focus on when re-considering your career and presenting yourself to employers. As a starting point, see the Employability and your future career pages.
