Gadol, maybe I was not clear, but I am suggesting something similar. I am not suggesting a diploma mill. I more and more prefer online because of dangers on campus. Another option is a local college with kids living at home. But this might protect from wild parties, but will not protect from hearing what professors are saying and you will never know. With online, I discuss with kids in real time when bad ideas are mentioned, both college and high school.
this is personal. In previous generation, I saw kids who already came as learners from MO schools, going thru college without apparent damage, but I am not so sure about those who were not so strong after high school. In this generation, kids who went to non-MO schools, are ready for overpriced “frum” colleges that are possibly a reasonable option if you can get a good discount. Otherwise, it is throwing a lot of money into the wind.
