I checked them after I'd submitted the survey. The only real words that I hadn't ticked were "regolith" (I was almost sure it was a real word, but I didn't know the meaning of it), "phoropter" (I believed it could be a piece of engineering terminology, but again didn't know the meaning) and "peristeronic" and "apricity" (I would have given better than evens that these were made up).
