I’m pretty sure PAVE also requires an exam and while the exam may not be quite as notoriously difficult, PAVE also requires you to have a year of clinical training in the US. I just looked and the school I went to apparently charges $52,500 for a PAVE year’s tuition and that doesn’t count any of your living expenses which they estimate to be an additional $22,000. So hope you have a spare $74,500 laying around from what the website suggests. Maybe St Matt’s has special arrangements for clinical years built in like other Caribbean schools or something, but it’s still going to cost money.
Also, PAVE isn’t accepted in every state, so if you went that route and ever needed to move to a state where that wasn’t accepted, you may run into problems. Maybe you wouldn’t ever move to those states where it isn’t accepted but something to consider.
Considering a unaccredited school should be your absolute last option. I wouldn’t recommend it if you have any other option. Do people make it work? Sure, some do. But it’s not easy.
