Importance of Senior Year Grades!?

<p>I generally have a clear record of straight A-s through much of high school with the exception of a B+ in AP Bio and Drivers ED(LOL...doesnt count in GPA though) up until now.</p>

<p>However, I am having a lot of trouble this year with Calc, and it's likely that i will end up with a B in the class =/ </p>

<p>I initially had trouble with Physics, but worked my butt off to bring my grade up to a 96 percent this quarter. Likewise with psych (although it's easy, my teacher takes off unnecessary points for essays and such)</p>

<p>But regardless, I am a business major applying to Penn...how badly would that reflect on me? I applied ED, I don't think I'll get in...but if I choose to apply to other schools after I get a decision, will it look bad if my grades drop somewhat during senior year?</p>

<p>If you mean that you will have one B, then there’s no issue.
You just don’t want to be one of those seniors in the uncomfortable position of explaining a bigger drop than that.</p>

<p>do you think getting two or three Bs is bad? (AP Political Science and AP English and possibly AP bio), and i have a 92.XX UW GPA with the most challenging courseload. (This year is tough :/)</p>
