I just took it, and here are some tips that I have-
The info guides mention that they added two sections (reading comp and situational assessment), but unless you look at the subtest breakout, you might not realize that they took away hidden figures and rotated blocks. I was actually looking forward to hidden figures; I do really well with that section.
The instrument comprehension test has much clearer graphics, but the questions seemed harder than what I remember or what is in any study guide. For example, in most study guides, the compass will point due east and two or three of the answer choices are pointing in a completely different direction- it was very easy to eliminate wrong answers or just find the one that was heading in the right direction. With the new test, it seemed like several of the answer choices were pointing in the right direction but had were more subtle differences in banking. Also, the graphics aren't in color like they are for the prep course that is provided from the AFPC site; they're black and white like the rest of the test. Just so you don't have to spend time looking closely to distinguish the details, if you're looking at a plane heading due north (away from you) in level flight, the image will appear darker gray, whereas a plane heading due south (toward you) in level flight will appear more white. Maybe that's a "duh" statement, but it took me a minute to make that distinction as I was looking at the sample problem. (You can also clearly see the cockpit when it's heading south; that should have been the giveaway for me.)
This is the same as the Form S of the AFOQT, but if you haven't used the prep materials from AFPC, then you'd be surprised at the table reading section. Most study guides state that you'll have to answer five questions finding coordinates for one little table of values (like you have five questions for one picture in the block counting section), but that's not at all accurate. There is one huge table that all of the questions are pulled from, and you aren't allowed to use anything to form a straight edge as you hunt for the values at the given coordinates. I highly recommend using the table and practice questions provided by AFPC.
As for the science section, it now focuses purely on physical science... a lot of chemistry, several astronomy questions, and some physics (at least for my version). I wish I had watched some YouTube videos to get a quick comprehensive review of these areas.
The situational assessment part was about what I expected; for several of them, I was between two answers for what the "most effective" option would be. The "least effective" solution was usually pretty easy to spot.
The reading comprehension subtest was all military-related text; it wasn't anything that I found difficult, but there are a couple that I went back and forth on.
I thought that I would have a better idea of how I did after the test (compared to how I felt when I took the S version in early 2014), but really, I'm not trying to guess at all what my scores will be... I was focused on improving my pilot scores to make them more competitive, but I think I did fine in all the other sections. Previous scores (recalculated to match T version of test):
Pilot: 42 (I should add that when I took this, I didn't study these sections hardly at all... I was familiar with instrument comprehension, but I ran out of time on the test and had to fill in "C" for about eight or nine of them. I didn't want to be a pilot at the time, so this didn't bother me.)
Nav: 82
Academic Aptitude: 93
Verbal: 96
Quantitative: 86
Best of luck to anyone taking the new version! Hope some of this info helped.
