High School Drag Racing Dilemma

Well guys, I earlier posted about my son winning. Through out this series he has either led or been in second place. Last night he won again, and is now tied for first! Heres my dilemma, the last points race is next friday. He graduates next Friday. He suggested missing graduation ( I DON'T THINK SO SCOOTER! ) His mom would kill us both. She did suggest showing up to get a tech card, thats 25 points, & then getting back for graduation. Well i just thought i'd like to hear your opinions. Maybe it will rain. HA HA!
