<p>Around what percent of classes are taught by TAs at Cornell? More specifically, how many of the bio classes are taught be them?</p>
<p>i think the only classes that are taught by TAs are the freshmen writing seminars (since there's like 50 or something of them and they want small classes), and some of the intro foreign language classes.</p>
<p>Only labs, writing seminars, and review sessions.</p>
<p>I believe all lectures are taught by professors.</p>
<p>The TA's I've had have been extremely good! Like I'm taking a medieval writing seminar right now, it's taught grad student. However, she did her bachellor's degree some time ago, and just went back to school, got her masters at Oxford in Medieval Studies and Theology (I think), and is working on her pHd at Cornell. It's one of my favorite classes.</p>
<p>My chem recitation TA (review sessions) is also great. . .although the professor is great, I think the way my TA presents things is even better. He really knows his stuff, as a researcher can tell us some really interesting research applications about what we're learning.</p>
<p>Chem lab TA's basicaly just oversee the lab and make sure no one is doing anything stupid, and clarifies basic instructions.</p>
<p>My bio lab TA last semester was fantastic, she was always really approachable, and even took some students out with her to do her some field studies for her research.</p>
<p>I've heard of a couple people that have gotten a bad TA in economics....just because she didn't speak English very well, but they were able to switch sections, and in most cases if you run into something like that, you can either officially switch sections or just go to another TA (most sections don't take attendence so if you find someone you like you can go to someone else if you want).</p>
