Bad test grade?!

<p>Quick question! I recently received a 78 on an advanced physics test and I am sort of freaking out..we will only have around 3 tests per quarter, and so I'm paranoid that now my average will end up in the 80's somewhere. I am applying ED to a selective college, and will be sending in first quarter grades when they're ready, a bit after my app is submitted. I've always been super strong in the sciences, and want to go the biology/chemistry route, but will a possible B for the first quarter of this course greatly harm my admission chances? Thanks for opinions/advice :( </p>

<p>If you get accepted/deferred/rejected, it will not be because of 1 B; there is much more that goes into most college applications than just grades.</p>

<p>thank you @skieurope</p>
