First of all, congratulations on having finally seen the light, and applied to transfer to a 4 year college!
A normal workload for a full time student for first semester of college is four courses, and only one with lab. Depending upon the college, that could be anywhere from 12-18 credit hours. Some highly motivated students might take 5 classes, even 5 classes plus a lab, but that’s not a good idea for you. Let’s see how you do the first semester, registering for a normal full-time student’s load, which is four classes, plus one lab if you’re doing a science class.
Your idea that you should take only one course a semester at the 4 yr college is absurd, and says that you’re terrified about transferring to the 4 yr college. Don’t be. If you were able to do the work and do well in community college, you’ll be able to do it in the 4 yr college, too. You need to realize that you are about ten years behind on the normal track for people who go to college, so it’s most definitely time to kick it into high gear, and get done.
You no longer go the community college advisor. You’re done with community college.
You’re transferring to a 4 yr college. You meet with the college advisor, at the college that you will be transferring to. Call on Monday and make an appointment with admissions, and with advising. I’m assuming that you’ve done this in time to start in January, but some schools start this Monday, so I’m afraid that you may not be able to get the transfer arranged in time. If you go into the office in-person, or have an online appointment with the office of admissions if they’ve gone remote, you may be able to expedite the transfer, since you already have a 2 yr degree.
Take only ONE class that has an accompanying lab. Take only ONE science class, plus three others. Do NOT try to take intro Bio and a higher level biology class at the same time; in fact, I’d be very surprised if they even were to let you register for any higher level Bio classes if you haven’t yet completed a year of college level intro Biology.
Your gen eds should have been satisfied by the community college degree, but talk with your advisor AT THE FOUR YEAR COLLEGE, not at the community college, and plan out your courses. The community college advisor knows NOTHING about what is required at the 4 year college that you will transfer to, other than perhaps knowing something about what that college might accept for transfer credit from the community college.
Have you decided on what you want to major in, what career goal you have? The reason I ask this is that, from your community college career and grades, I don’t think that med school, dental school, or PA school is a realistic goal for you. 3.5 is nice, but it’s not going to help get you into any of these, plus after the things you’ve said, it doesn’t seem that nursing is a good match for your personality, at least not patient contact nursing. But you do seem interested in science and math. Have you thought about doing some kind of ancillary medical field, such as the many different types of lab work, or radiation technology or radiation therapy, or such? You liked physics, and you do need to understand physics in order to any of the radiation or imaging fields. You get to do a lot of work independently, the patient contact is minimal, and the pay and job security are good (although not the astronomical level to which you seem to feel entitled). Does the 4 yr college that you’re transferring to have any degrees like that? Those are possibly realistic goals for you, that you could complete in 2-3 more years at a college, for a 4 yr degree with a smooth transition into a good-paying field.
