I graduated in August 2019 from the 5 quarter ABSN program - you will need to be available 7 days a week to complete this program, especially now that it is only 4 quarters. For our program first 2 quarters were up to 5 days per week, winter quarter included saturdays, spring quarter was 5 days per week and then senior practicum (summer quarter) we worked our nurses schedules plus had class on tuesdays, so you need to be available all 7 days. I hope this helps!
I just graduated from the ABSN program and would say that it isn't so much about your GPA or hours of experience - though the average pre-req is somewhere in the 3.7 or higher range usually and the volunteer hours is usually in the 650 range. Having said that it is more about what you do with this experience and how you articulate what you know about nursing from these experiences and what you learned from it. Good luck!
