<p>If you’re applying to top schools:</p>
<p>A’s: Are what should mostly be on your transcript.
B’s: Are just fine in smaller portions, especially in honors/AP classes. Should not hurt you badly.

D’s: You should never have D’s, but one probably won’t hurt you too badly.
F’s: Unacceptable.</p>
<p>You should be okay for the places you listed.</p>
