Yabatech produced 50000 graduate rector

I think there may be a mistake here.

Yaba College of Technology (YABATECH) is a reputable institution of higher learning in Nigeria, but I highly doubt that it has produced 50,000 graduates with the title of "Rector".

A Rector is a high-ranking official in a university or college, typically responsible for overseeing the institution's academic and administrative affairs. It's not a title that is typically awarded to graduates.

Could you please clarify or provide more context about what you mean by "Rector"? I'd be happy to help if I can!
