Late corrections

Sometimes you will discover mistakes in what you thought was a final draft, when you no longer have time to print out a corrected version. In such cases, you should hand-correct the printed version （that's one reason to double-space essays）. It's usually okay to turn in an essay with one or two such corrections. How to do it: Cross out the mistake with a single horizontal line. Mark the insertion point with a caret （^）. Neatly write in the correction above the printed line. Don't write below the line or in the margin. If you need to make a more substantial correction, make a clean printout.
