<p>steellord321: I’ve become really friendly with a couple of my GSIs (we’re even Facebook friends, haha) and had no issue asking them what they were teaching the next semester and what section they were going to teach. They e-mailed me the exact section once they found out for sure. GSIs are usually first or nearly first time teachers and I imagine that any sign of appreciation would be welcome, so usually they would be happy to share that info with you. As for how soon they find out, they know what they’re going to teach next semester before the end of the current semester usually, but I don’t know if they ever know the exact section yet. That you can just have them e-mail you about once they find out.</p>
