Yeah, I brushed up a bit on my vocabulary and mathematics when I was studying for the CFAT. I've used army-test to study and it worked out pretty great from my experience. You can use either the CFAT Practice app if you prefer studying with a mobile device, or army-test for PC. I believe both are made by the same people since on the army-test site it also linked towards the CFAT Practice app. However, both of them required you to pay their subscription in order to gain full access to them so it's up to you if you really want to spend a bit of cash. But it's really worth it at the end.
I'm not allowed to share or disclose any information about my experience or what type of questions they asked me during my interview and medical, but for the interview, just wear your formal clothes and have a general understanding of the trade you've picked. Also, be open and honest as well when answering their questions, same goes for the medical checkup.
