Based on what fact not just speculation? Yes the essays are important and especially at Michigan. But based on the last 3 years rejections I don’t think what you are saying is factual and can be misleading to applicants. Lots of similar students were rejected this year alone. Lots from California
But I do know someone that knows the UCs well. @sushiritto so if you write an awesome essay and have the stats are you accepted to Michigan? ?.
