On Saturday, all three levels of the CFA will be administered worldwide.
The CFA curriculum, which consists of three levels, is considered to be the hardest test on Wall Street. To put the exam's difficulty in perspective, fewer than 20% of candidates pass all three on the first attempt.
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.
