This is confusing

In Alex Kline's report on Sim Bhullar heading to New Mexico State, this perplexing quote appears:

“The school system is different in Canada compared to America,” stated Bhullar on Tuesday night. “I would not have been able to qualify because my grades from Canada were messed up.”

The NCAA doesn't have different standards for Ohio (Xavier) than New Mexico so was it an Xavier standard that forced Bhullar to look elsewhere?

PTW senses that Jason Groves will be on this one, digging for an explanation.
