Real feedback from I40AF candidates on Reddit.
"passed last week. studied like 4 days before it, not proud of that. the practice questions on sensor types actually saved me, kept mixing up inductive and capacitive before that. site didnt overcomplicate it, just repetition until it stuck."
"honestly wasnt sure id need to study at all since ive worked on this stuff for years, but the PLC basics section humbled me pretty fast. i40afexam.com had a mistake review thing that showed me i kept blanking on ladder logic terms. passed on my first try, still kinda relieved."
"procrastinated on this so hard. ended up doing the mock exam the weekend before and it mapped pretty close to the real test in terms of how questions were worded, especially the schematics stuff. wasnt confident walking in but it clicked enough to get me thru."
