New here and hoping for some great opinions!!

HI everyone!!! I am new to these forums found them while searching for information on nursing. Based on some of the posts in this forum, I can tell that everyone here are very supportive of eachother and have great respect as well.

Well to start off, I am a 20 year old male in Alberta and am going into my 3rd year of Nutrition and Food Science program this coming September. This is different than becoming a dietician, in case people are confused. I am considering a career in nursing after my 4th year in the nutrition program.

I have done a lot of information searching from university calendars and internet searches and am hoping for some more opinions from people. I found that you can do accelerated programs compared to regular 4 year programs. What I can't really picture is how you can finish a program in 2 years that is intended for 4 years and both take similar number of courses per semester. I AM NOT complaing about this at all!! I'm just wondering, won't the people taking the 2 year program miss some info that people in the 4 yr program receive?

Also, I read info from U Calgary and U Alberta calendars. Why is the UC one called a BN and UA one called BScN? I thought all nurses get a bachlor of science in nursing? Correct me if I am wrong.

Hopefully you guys dont bash me for asking such dumb questions. I dont know where else to put this. I look forward to hearing everyone's answers!! And to meet many great people on here.
