B.O.B

Its that time of the month again. Im pretty sure our class has a good understanding of this unit on Periodic functions. This unit was pretty easy I guess. Its just a matter of knowing which goes where and the word that helps us in "DABC"(dabic). Wait a moment, was'nt Mr K asking us if we were ready for this test. I never got the chance to ask if our test is really tomorow....Anyways good luck!!
