They give you an idea of what your schedule could be like in June, yes. Typically during first year, you'll have Fundamentals of Nursing on Mondays/Wednesdays. If you're taking Pathophysiology, you'll probably have that on Tuesdays. You have a four hour lab scheduled on Mon, Tues, or Wed. There's usually two tracks for lectures, A and B. One will have classes in the morning, so that allows you to choose an afternoon lab, the other is usually in the afternoon, so you can have lab in the AM. Whatever you can make work based on the nursing program's registration day (which is different from the rest of the college). Your clinicals will be on any day from Thursday to Saturday. Some had them all Saturday, I had mine Thursdays & Fridays. It'll be a busy time, so be mindful of that :)
I think you'll be able to register for classes sometime in August.
And awesome! I think I got a discount for scrubs too, can't remember. They told us to get white shoes for our cohort, but depending on your clinical instructor, some can be lenient. I wore tennies, then white crocs I could easily clean, and now I'm wearing black danskos for practicum and boy am I relieved (my feet are too). I did everything they told us to so I don't get in trouble during the first year (lol).
Anyway, relax! You got into nursing school. Enjoy this time before you basically have to put your life on hold for two years (or three, if you're doing OHSU or Linfield after). Although, we just had a panel of graduates who said OHSU is a ton easier than the things we had to do at PCC Either way, nursing school becomes your life and you'll experience a rollercoaster of ups and downs. If anything, brush up on your physiology!
