I've tryed the april 4 PGRE, I got a quite high mark but I want to do it again in October. I noticed that the test I've done had a quite similar style to the 0177's one, as someone said here about one month ago, and that there were many questions about mechanics, EM, and also quantum mechanics.
Since the 0177 test is the most recent one among the 4 known samples, I was wondering if recent PGRE tests tend in general to have these features in common. Otherwise it may happen that a recent PGRE is more similar to another of the 4 sample tests, having for example quite less calculus questions and requiring quite more knowledge in solid state physics. Can anybody confirm this hypothesis?
