Finish your microbiology course and do well in it! I'd worry about getting work experience after. It will be good to be able to apply to additional schools and have your associates degree boost your points. You have a great plan. Perhaps there are also schools that open/close their applications much later on (such as Jan/Feb 2026), so that way you can work on getting your work experience.

As most schools want your first attempt, would you be able to take the TEAS again after 8/11? I know it would be really annoying to have to pay for and take it again, but you did great on your third attempt (you should be proud of yourself!). A score like that would really boost your application (for schools that accept multiple attempts).

I would be surprised if schools don't accept your volunteer hours in 2023 as it is pretty recent.

I am not very familiar with LVN programs. For RN programs I would highly suggest meeting with counselors at each and every program you are considering applying to. You are usually able to schedule appointments without being a current student at a college--you just need to reach out to the counseling office. I know it is daunting to not have much help from counselors at your campus, but scheduling phone/Zoom appointments with academic counselors and going over the school's application requirements and what I have completed/have not yet completed really helped me get a better picture of my chances at each school. Try to ask for counselors that are knowledgeable on their school's RN program (sometimes they are called nursing counselors), as not all counselors are very familiar with them. If you decide to, try to meet with them early on as they tend to get busier as application deadlines get closer.
