Simple question about senior grades

<p>I am applying to top tier schools (HYPSM, etc.) and I'm getting ready to send my applications out soon. However, the grading period just ended and I have all As in all of my classes (all APs) except for my first B in physics c.
My school puts quarter grades on transcripts until final grades are published at the end of the year so all of the transcripts I have are going to show a B for the first quarter physics c grade...how much bearing (if any) do you think this will have on admissions? </p>

<p>thank you!</p>

<p>None whatsoever. Why do people feel a B is the kiss of dealth in Top 20 admissions?</p>
