On Saturday, they'll be taking the Level I exam of the CFA.
The CFA curriculum, which consists of three levels, is considered to be the hardest test on Wall Street. To put it in perspective, fewer than 20% of candidates pass all three on the first try.
The average test-taker also spends a solid five to six months preparing for the CFA.
Of course, every test-taker hopes things go smoothly and according to plan on exam day. But we've heard some crazy horror stories ranging from bathroom disasters to concentration-breaking distractions.
We've included them here. Make sure this doesn't happen to you.
