Had my MMI exactly 1 week ago and just got my offer through for Adult Nursing!! Ecstatic, already firmed it!! And also don't worry about the MMI, the people there are so lovely, it's so much less intimidating than you think it will be. I ended up laughing with my interviewer about something completely off topic, she was lovely.
Also to everybody asking about the literacy tests, we had to sign a non-disclosure form as not to say anything about them to other applicants! So that's why everyone is being kinda quiet, seriously they are fine anyway, as long as you found GCSE english okay you'll be fine.
