I got 89 in Computer in High School back then, my mother asked me why. Well...I don't know.
But that's the lowest I got in HS.
In College I got 2.75 in Philo 11(Logic). It was kind of a wrong move for me, because I should have taken Philo 1 first(which is a required subject) then I could take Philo 11 next for SSP's.
