<p>I heard that the Senior grades will only count until you got accepted to the schools. That time, they will ask to send the official transcript of your 4 full years of high school -so they will see that you haven’t procrastinate, still challenging yourself and preparing for college.</p>
<p>Most RD schools will ask for your first semester grades, and ED/EA will often ask to see your first interim grades. It’s very helpful if you have upward trend, and it looks really bad if your grades start to slip. Your grades will even be more important if you should need to get off waitlisted school(s). Of course, as mentioned by archi92, your admitted school will want to see your final senior grades.</p>
