Invited for degree interview

I’ve just had a letter inviting me for an interview at Westminster University. Yay! I was very concerned I’d applied too late. The letter says I should bring any ‘qualifictions’, which sound fun, and 15-20 images from my portfolio. Hum. Portfolio. Right. Don’t really have one, but I’m sure I can put something together. It needs to be ‘easily navigable both physically and thematically’, and I’ll be presenting it to the group for 5-10 minutes. I’m concerned others will have far more experience than me, mind, but there’s nothing I can do about that. The interview is a week today. I’d best get busy.
