I'm the second ROTP OCdt mentioned above. Enrolled a couple weeks before class, and like you don't really have anything to identify myself as being a member of the Forces yet. Don't sweat it though, as long as you have all your documentation squared away and your ULO isn't panicked, everything should come together relatively quickly. Being in the third year of my schooling, I think they are going to have me complete Mod 1 and 2 of BMOQ together, but if you're first or second year they might elect to split it up for you. From what I've experienced thus far, just stay on top of your classwork and keep checking your emails for updates from your ULO. As far as uniform goes, there isn't really anything we will need it for until we get to CFLRS, for your SEM ARV you just wear business casual. You're not alone, there are a few of us late top-up selections kicking around at civi u!!
