Welcome to CCN! I started the program this past July and I am now at the end of Trimester 1 - woo hoo! So far, it has been great for me. The nervous jitters are normal. It does seem disorganized a lot of the time - but so far everything has ended up working out fine for me. I really like the online format - but just as a word of advice - keep up with the reading!
Anyway, congrats on the acceptance. If you have any questions, feel free to PM me - I'll try to answer the best I can.
