Congratulations!!!!
I think we may not need to make decision on the spot. However, unless u have previous units credits, u may have to do all the required units. U can pay on the spot & that is probably why they asked u to bring credit card etc. I also think we are getting our student cards...
Money aside, I think u got to really think what job is more interesting to u.
Personally, I cant handle looking into someone else's mouth all the time! Imagine u just had a nice lunch, your patient came in , opened his/her mouth & all the teeth are stained with tobacco! Yuk!
