<p>I think that your chances look very good. I would not be surprised if you were accepted, if you apply SCEA. In your particular case, it seems to me that you have extremely high odds of deferral SCEA, if you are not accepted right away. </p>
<p>With regard to standardized tests, in my opinion, you have plenty of them, and high enough scores. I don’t think that SAT II scores in Latin or Literature would add much to your application.</p>
<p>I think that the decision about applying SCEA or not largely comes down to the essays, in your case. Essays do tend to improve over time. When the SCEA deadline rolls around, if you are happy with the essays that you’ve written for Stanford, including the shorter answers, then I’d suggest going ahead. If you realistically think that you have the ideas and the time to improve on them, then you could hold off till RD.</p>
