This was me. I entered a hospital-based LPN program at 16 and proceeded to have the stuffing knocked out of me. I grew up...FAST. I graduated at 17 and sat for my boards the day after my 18th birthday. If my birthday had been even a day later, I would've been forced to wait the 4 or 6 months until state boards were held again. Yes, this was in the 80's, which makes me a COB.
My first job was on a Med-Surg floor of the hospital that offered the LPN program. I wanted to work 3rd shift as a GPN, but couldn't, as I needed a work permit. Yes, I was embarrassed.
I went right into an ADN program immediately after I finished the LPN program in July. My birthday is at the end of September, which means I was 17 for the first few weeks of the ADN program. I vaguely remember discussing it with my first CI, and I think I was able to start clinicals because I had already graduated from the PN program. If I hadn't passed my boards on the first try, however, I think I would've been jettisoned from the ADN program pretty quickly.
If I had the opportunity to start over, I probably would have taken more courses at a community college, perhaps studied abroad for a semester, or any one of the exciting things that I could have done in those "pre-mortgage/relationship/marriage/kids/life/etc" years. I don't regret going into Nursing, but I do wish that I hadn't been so gosh darned impatient.
My son is in a similar situation, as he participated in a dual enrollment program at the community college where I currently teach. Starting in his sophomore year in HS, he took college level courses and received both HS and college credits. He graduated from HS in June 2016, and had enough college credits to transfer to an Engineering program...if he wanted. Instead, we've encouraged him to take courses that "sounded neat" as well as pursuing anything that he had ever thought to himself, "I wonder what it would be like to..." He took an introductory piano class...and quickly learned that he's better suited as a music aficionado rather than a musician. He took an ASL class and earned himself a "therapeutic F" by ignoring the syllabus, and replaced the F with an A by repeating the course (paid 100% out of his own pocket, too.) This semester, he's taking a heavy math and science course load, as well as a fencing class. I'm doing my best to encourage him, but inwardly cringing as well. All of these experiences are helping him develop skills and insight that are setting him up to be a much more successful, well-rounded Engineering student.
I understand your daughter's desire to forge ahead and finish college as quickly as possible. I felt the same way. However, she has opportunities available to her that are quite unique, given her age. My suggestion would be to choose some situations she had never imagined experiencing...and experience them. She has the time to take classes for the sake of satisfying her curiosity, trying something entirely new, without worrying about completing a degree on a strict timeline. (I agree, however, that she needs to be aware of any financial aid limits, and consider taking courses through a community college or utilizing private scholarships.)
Good luck to her!
