Sometimes it is necessary to reset your class points such as the start of term. (Please note - this can only be done by teachers!)

To reset, open J2stars, and select the "settings" option:

Within the settings area, click the "points" menu. Here you will be able to reset points for the whole school : 

Please note - It is not possible to reset points for individual classes. However you can view points awarded in the last month/week/day. To do this, select the class you wish to view, then click settings. Here you will be given the option to select the time frame for your class points (monthly, weekly or daily)
