Overall I thought it was very solid, there were minor things I think that I would have liked improved upon. Such as some type of periodical studying mechanism, I used a 3rd party program for that myself, that focuses on retention. Like asks you things you struggled on more frequently than things you don't. Optional of course. The biggest gripe I had wasn't that big but I was fairly annoyed when it happened there were two "final" tests of sorts one was just for studying, 200 questions or so the other was the one that is required to pass to take your test. I took the 200 question one a dozen or more times til I passed it then realizing it didn't give me the thing I needed to go take my test, which did help a fair amount for studying but then I felt rushed and pressured to pass the other one.
