| even calculations are recommended in pen, raller. When you cross out, a simple line through what you don't want graded will do. Don't scribble the thing out and make a gash in your paper from where you were trying to cross out. I do all my calculus work in pen (it drives my calc teacher nuts) but when I do something wrong, I cross it out and start in a new area. In a way, this looks cleaner and is easier to read. When you erase with a pencil, you may leave eraser marks and then write over those eraser marks which makes it hard to read. I personally abhor the pencil and I always write everything in blue ballpoint pen.
edit: I will be taking Calc this year but I did take Chem last year and we were required to write in pen. Just a note. |
