Hey guys I just completed ACS testing a few days ago, passed for all three trades (Pilot, ACSO, and AEC), and thought I should share my experience and some thoughts on them.
First my background:
Trade Pref: AEC (chose only AEC)
Applied: Jun 03 2018
First Contact: June 04 2018
CFAT: July 5 2018
Medical Part 1: July 5 2018

ACS dates confirmed: July 16 2018 (Was not given options, was told my ACS testing was on Nov 15-16)
Interview: Aug 14 2018
Medical Part 2: Aug 14 2018
ACS testing: Nov 15-16
First thing first, I cannot share anything about the content of the test itself, but I can only tell you, that the only thing you can realistically prepare for are mental arithmetic (and be sure to be ready to answer them fast). This is coming from a guy with fresh memory who just wrote the test. The test itself is honestly about testing your aptitude, and it is not meant to be "easy as a result of a good prep". Also, it has been mentioned a numerous times on this thread, but speedtimedistance.info helps. A ton.
The test will be hard, and you will, 100% think that you failed. But do not worry, everyone (at least everyone at my ACS) thought they did. There will be components of the test where you will, most likely, have guessed all of the questions, and would have had 0 idea of what you just did. Do not worry, I felt that, and guessed the majority of the questions on 2 tests, and I still passed for all three trades.
So my point is, the testing is done over two days, and please, do not give up. After the first day, don't think about how poorly you did (because you didn't) and let that feeling eat away your precious sleep time. Get good amount of sleep, that is the best prep you can ever do.
In terms of how many people passed at my ACS? I don't know the exact number so don't quote me on this, but while I was sitting around the lounge waiting for results, most of us shared our results (of course, not all of us did, and they had all the rights not to):
There were 18 of us, and about 11-12 guys shared their results, and here's what I've understood:
5 people passed for all three trades
1 have passed for only ACSO
3 have passed for only AEC
So there's a good pass rate, you may not have gotten what you wanted, but majority of us still passed for, at least one trade.
And lastly, enjoy your time in Trenton! The staff and the people around you writing the test are all nice people and make yourself comfortable and good luck on your tests!!
