Since most assignments are given with plenty of time allowed to prepare them, post as early as possible. It's best for you and whoever will answer you. Sometimes a few more words will help. Sometimes an extra sentence will make things clearer. Sometimes it will help if you quote a line, or cite the Act and scene you're referring to.
People appreciate being appreciated.
