I'm wondering if anyone has experienced a rise in grades at school or university since going primal? Or perhaps better results at work etc?

My grades have improved since being primal and becoming more physically active, although my study habits haven't really changed.

Grades before: 4's and 5's ( Passes and Credits)
Grades on primal: 6's and 7's (Distinctions and High distinctions)

[ my uni is graded: Fail, Pass conceded, Pass, Credit, Distinction, High Distinction ]

Anyone else have similar results?
