Yeah my school had this survey and called people down, the usual time takes like 5 minutes, mine took 35. The guy who I had was pretty nice tho and was studying to be a psychologist which is why we were called down. He seemed pretty cool with it because he didnt say anything the whole time i was trying to get my words out which was great. But i was also lightheaded at the end of mine too. I hope your thing works out man <3
