I'm supposed to start ADSC today 17th (get there by 11:00) but in my head it was the 18th, I even told a recruiter it was on the 18th when I went to ADSC briefing and took time off work. I didn't actually have the letter, my mum had it at hers (long story) but she text messaged me a pic of the letter last month with all the information. I just called my recruiter and he said he is going to call ADSC but he said I could get a 3 month deferral, that's what usually happens to people who miss it. I'm devastated I've got my 1.5 run time down by just over 2 minutes in a month, practiced my maths revision, ice breaker etc. I felt suitably prepared for it, only to look at my train tickets and see the 17th to my horror. Will I definitely have to wait 3 months even though I'm a dumb shit?
