If you are still confused you should do a few things:
1. Watch the Orientation Video or watch any of the other relevant videos on this support site.
2. Email your teacher, they are here to help you. Give you teacher 24 hours to respond on school days. Remember in the summer, teachers have the weekend off too. They will respond during school hours on school days Mondays thru Thursdays.
3. Rather see your teacher face to face or need something answered right away? Come to school during school hours anytime that is convenient for you. Even though you haven't known them for very long, your teachers are all highly qualified CUSD teachers that are here to help you. Teachers are available Mondays-Thursdays during regular school hours.
