If you're asking if you can sell your leave, the answer is no (not unless you're getting out of the navy, which is a bad deal anyway, because if you sell 30 days of leave, you'll get one months base pay, if you take 30 days of leave, you'll get a month's base pay, BAH, and BAS). For BDCP, you guys shouldn't worry about these things, since while you're in school, you'll never be in a position to have to drop a leave chit, so if you lose some leave, you'll still come out of OCS with 60 days of leave, which is 52.5 more than I had.
