There were back when I took the written a few questions that just couldn't be answered (doesn't anybody at the FAA proofread these things by actually trying to take the tests as PUBLISHED?). It was my understanding if you got one of these questions on the test, you got a pass on it.
I have seen credit for one of these "gimme" questions before, since I took the stupid instrument written three times and passed it each time. It was marked as not scored on the final result sheet.
The problem is, to get them onto that status, someone has to report them. That means at least some people will not bother and miss them until someone who cares takes extra time out of their day to go fix the FAA's screwup.
And let's say I'd bothered to memorize which question it was, that I knew couldn't be answered correctly, and then I walk out and get a note in the scoresheet that it didn't count anyway...?
Waste of f---ing time by people who could easily fix it up front with only slightly more effort.
Why they don't just remove the damn things from the question pool altogether when they're reported and confirmed is beyond me. It's obviously a left over from printed test books.
The test center software can't possibly be smart enough to be able to tell you the question ended up a "gimme", but not smart enough to simply remove it from the pool. Sheesh. It's a freaking computer, not a printed piece of paper. Just send out an update and delete the damn thing.
They're so stuck in the 1950s it's beyond annoying, it's just sad. But hey...
ADS-B is so slow it still can only send you METARs instead of, oh... Plain text. That'd be way too modern. LOL. Yay old crap!
(Cue some one here posting his opinion that he loves METARs for their brevity and consistency, because they had to learn them... While every other hobby on the planet switched to weather described in English with even upper and lower case and punctuation decades ago. Hell, I bet boaters, race car drivers, and the like, can get it in a choice of languages, even. But we just have to stick to tradition and teletype shorthand in aviation, the place where technology goes to die inside a "certification" process that lasts years and multiplies the cost by 10.)
So yeah... Taking the written three times, not recommended. Ha. It just serves to annoy at how outdated and useless most of the material is, and highlights the awful wording and bad questions that are meaningless.
Best to go get the flying done so you don't get two extra shots at being totally annoyed at the hideous quality level of the test you're taking that is supposedly important information you need to stay alive, but is sprinkled with stupid RMI questions from the mid-1970s... And even then, stupid stuff like "which way do you turn the knob" when in the real world, there's instant feedback if you turned it the wrong way, and your fingers will naturally just reverse when your eyeballs see the needle going the wrong direction.
