Can you guys help me with my IA please?

Hey guys! I would be forever grateful if you guys would fill this survey out for me. My IA has to do with whether or not there is a correlation in GPA and ranking on the ladder. The sample size that I want is around 150 and I do not know that many people at my school who play this game. Thank you in advance. https://www.surveymonkey.com/s/B86S2V8
