People often say Haas requires a certain amount of luck to get in, but if you do well in all areas, you are very likely to get in.
By do well, that means a GPA 3.9+ (average GPA is 3.84, but it is not the median, median is likely around 3.9+), complete all the prereqs and breadth requirements by the time you apply in fall (this would force you to take a heavy course load), write great essays, and find an internship or something you’re very passionate about.
Everybody I know who has met all of those criteria has gotten into Haas. Those who didn’t were always lacking someway whether it was a high GPA, but poor course load, or great stats, but poor essays.
