If you're asking such a general question 13 hours before a test.. your best bet is jacking yourself up on caffeine and possibly methylphenidate salts if you can get them (everyone here has ADHD so I'm sure you can), and digging into your studying. Fuck sleep, fuck everything. If you have ever taken a statistics class, you can learn this in 13 hours. Good luck. Don't listen to 90% of people here, if they even knew what Black-Scholes is, they wouldn't be doing FDs.

I took your advice, forgot my calculator and could only answer the multiple choice questions and draw some strategies.
