So do you mean you HAVE just finished a year at Aston???

Personally i would come clean, express your skills strongly and be optamistic that you can take on new tasks or adjust your skills to suit the job.

If they don't want you atleast you'll know rather than getting the job and getting the push a week later and feeling like at tit.

If your honest then if something does pop up that you aren't able to do you can say so and learn how to.

Hope it goes well.
