Should I write a letter to a school explaining my bad grades?

<p>I got a C in my senior year first semester in AP biology. Should I write to the privates that I applied to explaining my bad grade or will it look like I'm trying to make excuses? My sister strongly recommends this. My GPA is a 3.6 weighted with 4 APs. And if i should write a letter, how should I start it?</p>

<p>I wouldn’t do it. What is the mid year grade for your AP Bio class? Don’t worry about one “C”.</p>

<p>I agree lol they will prob let you slide with one c as long as the rest of ur grades are good.</p>
