"did the practice tests on acuiexam.com the weekend before, focused on assemble since constraints always trip me up. passed with room to spare. wasnt expecting much tbh but the mistake review actually showed me why i kept messing up mate constraints."

"procrastinated on this hard, had like 4 days left and barely touched sketch stuff. ran thru the mock exam a couple times and it lined up close enough to the real thing that i wasnt totally lost during the sketch section. passed, quietly relieved honestly."

"was skeptical at first since ive used free question dumps before that were garbage. this one broke things down by section so i could see i was weak on document and workspace navigation specifically. fixed that up over a week and got thru it fine."
