Many times we get that rush when we are finished with a piece of homework or a long project. We know we wrote brilliantly. There is no need to reread..or is there?
Even published writers must reread every time they write. We all have those brain-freeze moments when we use the wrong word, forget words, or muddle our best thinking! Reread everything every time you write and all of your grades will improve. Your stamina will also improve. Just remember--don't beat yourself up when you find "stupid" errors. Everyone makes them. Call them something else. Let it go.
