First, there are plenty of kids without internet access.
Next, why is it that kids in those well off school districts have such better test scores? Are they really that much smarter? Or is it possible that all of those life advantages contribute to being better prepared for schooling/testing?
Also, why assume a lot of TO kids will struggle with the rigor? I know plenty of students who struggle with the rigor - many parents of high achieving kids in these threads have shared the stories.
A friend’s D is TO at a private college and is thriving. Freshman year she struggled, but she utilized the tutoring services and had a great counselor to get her steady.
If it diversifies colleges and assists kids who are capable but without the early life advantages to meet certain test standards, I say give it a try and let’s see the results.
