I have a newish little thing that I do. That is writing all the assignments for the day that I have to turn in and crossing it off when it is sent in. Do you ever go to bed then while your laying there remember something you were supposed to send in or maybe homework you forgot about? Um this has happened to me way to many times. So when there is a problem you have to find a solution. *lightbulb moment* Post-its!
I just stick mine on my desk and throughout the day write on it. Another choicr would be to use an index card. An index card would be the better choice if you go to a brick and morter school.
There you go!
