Yooo
I had a friend just last year in a similar position to you having a below 'average' UKCAT, but because of her Gcse's, High a level predictions and a solid personal statement she got an interview from UOB - later getting an unconditional offer. Just read this thread and thought I'd let you all know as I know how stressful it can get just anxiously waiting haha
==disclaimer a lot of my friends also had to take a gap year and reapply, so it depends on the overall application.
