If you are in the way of needing pencils, I highly recommend the Bic Velocity pencil #2. I like the .9 lead, personally.
I'm generally not a pencil fan, but I have to have them for filling in the bubble sheets for exams at the university, and since I'm renting my text books when possible, I have to be able to go back and erase my notes so I don't get hit with the purchase price on books, so pencils are the go-to margin scrawlers for me.
Not all text books are available for bargain rentals, but I got lucky in this case.
