Don't worry, you'll get the hang of it in no time! I just started my journey in the OTEC cohort and highly recommend it. We're the online version of the ETEC master's because at least half of us live off-island and the rest have time constraints that prevent them attending traditional classes. Good luck!
It's going pretty fast for me too, but I'm learning so much. Trello is new for me too, and I love it. I go to the Trello Board before the Wiki, because I like how it's organized. It helps me to oraganize.
