I was watching this video and at 41:05 secs the professor uses this phrase Bolting for the Door . Does it mean that students will get bored or it will be too difficult for the students such that they will be eager to go out as soon as possible ?
P.S : Searching google for "bolt for the door" didn't provide encouraging answers.
The full context of the quote is:
By the time we get to the end of this class you folks are going to be bolting for the door because we are going to do some good math today. It's actually fun math, I think, but it is challenging.
