Hey @Lizzyny! Maybe! what classes are you taking now? Also, wouldn't it be easier to take 425 first? Doesn't 426 build off of what they teach in 425? I think it says you need to already have taken 426 before you can take 420, at least that's what it states on that RN roadmap they have on the site.
Regarding applying, from what I understand, you can apply for the program the semester after you complete all pre-reqs. At least, that's what it looks like everyone is stating. I'm finishing my pre-reqs right now (Spring 19) so I wouldn't be able to apply until Fall of 2019 for Spring 2020, which sucks but what can we do -_-
