<p>First of all, how are you getting an AI of 9/9?</p>
<p>A rank of 5% (your highest estimate) keeps you from getting a 9/9 AI, even if you have perfect 800s as scores. You might want to provide your stats.</p>
<p>As for your question about grades, your B’s will not help your application. But these B’s would need to be assessed in context of rigor and in context of class rank. I know there are debates on CC about the importance of rank, I am one who believes that rank is important to Harvard.</p>
<p>In the end though, if your application is compelling and appeals to Harvard. B’s alone will not keep you from being accepted.</p>
<p>The adcoms will read the transcripts to know how many classes you and the other applicants took.</p>
<p>Yes, the adcoms will read your mid-year report if it comes in January. Application files are still being collated and organized through January.</p>
<p>Strive for those A’s first semester in order to demonstrate an upward rise in grades and increased academic maturity.</p>
<p>Your GC’s report will address the academic rigor of your course selections and put in context of your graduating class and or those classes prior to yours.</p>
