If UT-Austin has a 40% acceptance rate, why do people claim it's impossible to get into?

Thank you for the replies. I suspected that the forced admission of all top 6% of schools was the reason for the wonky stats. That is a shame for Texas. I would understand if they were compelled to accept 80-90% of the overall highest achieving students in Texas regardless of high school, but it appears that some legislators are helping their hometowns at the expense of the schools’s ranking. My SIL almost regrets moving to a neighborhood with a great school because it put her kids at a disadvantage of getting in UT (she doesn’t really, but it is ironic). I’m not sure a 35ACT will get OOS admission now. My daughter told me last night a boy from a local private school with a 35 ACT, NMF, valedictorian, all state football, president of his class, many volunteer hours, accepted to Vandy, UVA, Emory, etc., didn’t get into UTexas. I think she will save her $70 admission fee. Thank you again for the replies.
