Failing out of college can be life-ruining. Tens or hundreds of thousands of dollars of high-interest non-dischargeable debt and employment opportunities completely nuked.

Come on, let's be serious. Most Stanford undergraduate courses aren't that tough, grade inflation is rampant, and almost anyone who gets admitted can probably graduate regardless of accommodations or lack thereof. We're talking about the difference between getting an A or A- here. And Stanford has such generous financial aid that students from families earning less than $150K get free tuition so no one should be leaving with huge student debts.
