Hi, Nicole! To clear up a few questions: LPN -BSN means that you're an LPN going on to complete your studies to becom an RN with a BSN degree. The RN-BSN means that you're an RN (Diploma grad. or Associate Degree) going for your BSN. For example, I'd been an LPN who went on for her BSN.....after my boss did a 'two step' on me.
Yes, you can work as a tech while in school! It wouldn't hurt.
As for math, you need some. I am sure your local Community College would help.
