<p>I agree with UCB that Math AP in 9th sounds very advanced compared to the national norm. There are probably less than 1% of all 9th graders in the nation that fit this.</p>
<p>10th seems early but doable while 11th is much more common.</p>
<p>In our area, AP world history is common for 10th, and Chemistry is rare since they won’t let students take chemistry AP until the second year of chemistry and they dont allow first year until preap bio is done. So essentially it is a sequence which holds someone back in chem until 11th.</p>
<p>In Texas, anyone in the middle of the class gets eliminated from flagship admssion consideration. So for a texas kid, second option works much better. However, I would not send my kid there since it does not sound challenging.</p>
