My students are receiving a pizza party monthly if they earn 5000 XPs for each month. Last month, 3 students didn't make the goal and weren't invited to the party. Last Friday when the students left my room, they had no higher than 6050 XPs. By the afternoon, they had 14,000 to 15,000 and were all saying they made the pizza party. I suspect they got a hold of my teacher partner's computer in his room and helped themselves. Is there a way to set the XPs back to where they were before last Friday afternoon? Thank you in advance for any help you can give me!
