"almost didnt bother studying for this and just winged the pnp vs npn wiring stuff on the fly. bad idea. went back and drilled it on fstexam.com the weekend before, passed with room to spare. the circuit questions were basically the same flavor as the real thing."

"was pretty skeptical going in ngl, figured these prep sites are all the same. ended up actually using the mistake review feature alot, it kept flagging how bad i was at hysteresis and switching distance questions until it finally clicked. passed first try, kinda relieved honestly."

"procrastinated the whole course and had like 4 days left before my exam. ran thru a bunch of the practice sets focused on sensor selection for different object materials, that part alone covered half the test. scraped by but i passed."
