<p>So for Chem 14B, or any college class in general, if the average is 68-70% and if that were assigned a B-, what's an A-? Is it 10% above that? ..80%?</p>
<p>Thanks.</p>
<p>What's the standard deviation?</p>
<p>usually its a standard deviation above.</p>
<p>i wish our mean was set to a b-. no, it is set to a literal F.</p>
