I was admitted to the College of Natural Resources and we have 4 CalSO dates:
June 16-17 (last two days of my last week of high school...don't want to miss)
June 20-21 (June 20 is my graduation)
June 23-24 (I checked it 15 minutes ago and it was still open...refreshed the page 5 minutes later...and it's full. DARNIT!!!!!!!!!!!!!!!)
June 27-28 (My only option)
I know that enrolling in classes at CalSO is FIRST COME, FIRST SERVE and I don't want to be screwed since I'll be attending the last CalSO date.
Any advice? Is attending the earliest possible CalSO date absolutely critical to obtain the classes you want? Or is everyone pretty much able to get the classes they want?
I'll consider missing my last two days of high school if attending the last CalSO session will truly screw me over for enrollment in classes...maybe.
Any advice about anything is appreciated!

Thank you!
