Is 10% A's about right for an OChem class?
Depends on the school, professor, history of the class with said professor/school, etc.
Essentially, nothing is normal. My class had 25% As (and 45% Ws). Some friends of mine had O chem with less than 10 % As.
Is 10% A's about right for an OChem class?
Depends on prof.
One prof in my class had about 30% A's.
The other curved from 80%-100% was an A and only 10% were part of that A.
