Apollo student Peter Bergstrom tweeted Wednesday morning that his chemistry teacher, Heather Johnson, agreed to give his entire class one extra credit point for every 90 retweets he got on his picture of the two shaking hands. So far, the class is getting a lot of help.

As of Thursday morning, Bergstrom had generated nearly 1,100 retweets and racked up twelve extra credit points for his class. Even Vikings wide receiver Stefon Diggs got in on the act.

Bergstrom is a junior safety and wide receiver for the Eagles football team. With the retweets, students are getting a 13 point head start on their final exam.
