How many can one take in one sitting?

<p>I know you can take 3 or so?? in one sitting by Collegeboard's rules, but what is reasonable? How long does one Sat II take on average? Would I go crazy if I decided to take 3 in one day?</p>

<p>You can take three on one day, and each exam is one hour long. You won’t go crazy, lots of people take three at once.</p>
