<p>how strictly to colleges enforce only sending in recommendations from 11th and 12th grade teachers? I had my ap calc ab teacher in 10th grade, and for algebra in 9th, and I'd love to get a letter of rec from him.</p>
<p>Generally, when colleges ask for recs from 11th and 12th grade teachers, don't submit recs from 9th or 10th grade teachers. You may send a supplementary letter from your AP Calc AB teacher.</p>
<p>yeah, it will look suspicious to them--as if you didn't perform well enough to manage to get a rec from a teacher who knows who you are right now</p>
<p>IF you school specifically says "only 11th and 12th" then only send those scores. However, I saw few if any schools that said this. People generally recommend Jr and Sr year teachers because they've known you most recently, but if you have a compelling reason to ask a soph teacher, and the school doesn't state otherwise, then you can send it.</p>
<p>That whole 12th grade teacher bit is ridiculous. There is no way (but exceptions obviously) a senior year teacher could know you as well as a 10th grade teacher if you've only had them for a few months.</p>
<p>Actually, I got a rec from a senior teacher, and I don't think it hurt me at all. Though I do agree that generally, 10th grade teachers could know you better...but really, it's hard to argue which is more important: length they've known you, or how current their knowledge is. My other rec was a teacher I had for 11th, 12th, and as a leader of a major EC, which was really ideal beyond belief. But I also considered a 10th grade teacher who I still knew well due to an EC, and a teacher I had for both 10th and 12th. Both of those probably look, on paper, like better choices, but ultimately the senior teacher was the best for the job.</p>
