I agree with people who say to get more certifications (maybe even now) which can get you jobs and experience- like phlebotomy, perhaps. If you were to work in a retail pharmacy, phlebotomy would be a good skill.
Seminary isn’t just for recent high school graduates! A bunch of my friends just went as tutors to one of the seminaries mentioned above- there are classes on all levels and they had an amazing time.
Unless you’re graduating now, don’t give up finding a job! Contact the career center or bio/chem department heads at your college- they’re there to help with that kind of thing. You may even want to get an unpaid internship if it’ll help you get really valuable experience. (I assume this is a gap year while you apply? If so, then getting experience is an excellent idea.)
