At age 40 I have been accepted into an accelerated BSN program. It has always been a dream that I'm finally able to pursue. I will finish when I'm 42. You're never too old!
I took each of these in separate semesters with a non-science/math class due to the amount of time required to do well in each. More than one of my classmates did take them at the same time and said they regretted it but did it for the same reasons you are.
