First of all, congratulations for scoring 1 in CASPER section as I personally thought that was the most difficult section. Also, you sound super young with lots of time to get into nursing if you're only in second year. Good for you for already knowing what you want to do and applying to the BSN program.
"Any advice on activities those of you that got accepted put down on the supplemental application would be much appreciated! Also did you focus on one activity or multiple for each question."
I'm just going to answer your questions in order. I think I filled out only 5 jobs in the employment section even though there was more space. 3 out of 5 were all healthcare related and paid jobs, the other two unrelated to healthcare (Starbucks and Quizno's, LOL). The activity questions, I didn't mention too many for each question - just maybe 2-3 activities that helped me explain my answer. I tried not to repeat activities because there were other extra-curriculars that I wanted to talk about that didn't get mentioned. I didn't list any research experience because I heard it didn't give many points so I used the limited space for other activities. I'd be interested in knowing how others who listed research experience scored.
"Also, what was your GPA?"
my GPA was >90%
"There wasn't a specific combo of scores required on the application to get in was there (for example 1's in all three categories)?"
I received an offer, and my profile was 1 (GPA) 2 (supplemental) 2 (CASPER).
I think you are already ahead of the game. I think you will do great next year if you improve on GPA and try to get more healthcare experience. I am still amazed you scored so high on CASPER!
Okay, now I have a question about the course registration
Usually, if there are multiple sections, you have to specify which section you want to register on SSC, right? - even if the timetable is standardized.
I see multiple courses that are each taking place in several lecture halls (so multiple sections), but all I can pick is the entire course? It seems like for Nursing, I just pick the STT and that's it...?
