how good do grades have to be after your accepted

<p>Let's just say I get accepted to Williams on December 15th. I've maintained a 3.96 taking tough classes in high school. How good would my 1st sememster and for that matter 2nd semester grades have to be to stay accepted?</p>

<p>In other words what's the biggest drop that's still accceptable?</p>

<p>A friend of my son went from straight As to As and Bs in IB. Overall average dropped from above 95 to 92ish. No probs at Tufts. I have no other data.</p>

<p>I think 2 or 3 of my 6 grades went down a half letter grade. I’d say relax, but don’t slack off too much. If one class is giving you grief (BC Calc for me hahaha), then one drop from A/A- to B-/C+ won’t rescind your acceptance. If more than half of your grades drop, then admissions might be questioning.</p>

<p>This is mostly speculative, but I think I’m probably on the right track. I know that all of my friends still put some effort into their second semester work and still went to the same school to which they committed.</p>
