(^1) You may use a pencil, but there’s no need ... you should not erase incorrect work, you should cross it out. Not only does crossing out
take less time than erasing, but if you erase by mistake, you lose all your work. But, if you change your mind about crossing something out, just
circle your work and write the reader a note: “Grade this!”
