If the test is like it was back before the Plague, it isn't hard for anyone who knows what they're doing. If you've spent the last few years just punching the send button and not doing the actual thing you're probably gonna be hurting. Study the basics.
Protip: READ THE QUESTION, then READ IT AGAIN. I've seen a lot of guys go down in flames because they assumed the question was obvious. I'm not saying they're "gotcha" questions, but they ARE worded in such a way where if you're walking in thinking you've got the ASA guide memorized and you've aced it before you pick up the pencil, you ain't making it to round 2.
Good luck! With the rate we are going to be taking on airplanes in the next few years, I expect a steady stream of hiring, in my opinion.
