Ahhh come on. It's not like things haven't changed over the years. Remember when grades were :

A
B
C
D
E
F
And then the stupid kids complained and they said "Well, an 89 is kind of like an A, we'll call it an A-..." So they lowered the bar just a little?
.............errrrrrrrrrrrr.................NO!

A = 70% +
B = 60~70%
C = 50~60%
D = 45~50%
E = 40~45%
F = <40%

That spread makes the school look good

Also...........just try getting 90% in a language with NO multichoice papers?

Or English Literature & History for that matter?
