No reading list will be the equivalent of an undergrad degree. I'll caveat that maybe it can do what she says and let you walk away with knowledge equivalent to some degree from some university, but knowledge is not all you get from the degree.

I did get an undergrad Philosophy BA more than 10 years ago. Take my experiences with a grain of salt because I'm practically addicted to education in a way that probably goes strongly against the current in a place like this full of people who self-taught vocational skills (I did undergrad in Biology, Philosophy, and Applied Mathematics after originally starting in Studio Art but giving up, then did grad work in Public Policy, Finance, Computer Science, and Cybersecurity, so I am severely over-educated and love education). To be perfectly honest, I barely remember the "knowledge" of philosophy in terms of just memorizing the history of the western canon and who believed what.

To me, the actual value in studying philosophy formally came from the practice. Reading the entire multi-century history of lines of thought. Seeing all the different angles that different thinkers approached a question from. Seeing a dialog in terms of one thinker directly responding to the arguments of another, and then again in the other direction. Much of that can't always be found in books and is better found in papers because that is how philosophers are publicly debating each other. To really internalize this, you need to not only read, but also write. Making my own arguments and having them publicly critiqued was tremendously valuable, especially when these were purely formal "take one side and give the best you can" and not married to my personal beliefs and ideologies such that I could not take criticism. Learn to see the flaws and the holes in human thinking, including your own.

Studied right, philosophy can be incredibly humbling. It is quite different from studying the creation of software or physics where there have been so many wild successes and great leaps forward of human achievement. It is the exact opposite. You come to grips with what are very likely hard limits on human understanding. You see that the very best minds we have ever produced have been asking exactly the same questions for as long as we've had writing and we're no closer to having answers after at least 5000 years of this. A lot of people would see that and ask well, what's the point then? It's intellectual navel gazing that can never accomplish anything. But being intellectually humbled is itself an accomplishment. Learn to appreciate that the human mind is not almighty. On a similar note, study statistics, because done right, that will teach you much the same thing, how impressively we can estimate and come with good guesses, but hard limits on what we can ever really know.

That said, is it worth spending a whole lot of money on getting this education and getting a philosophy degree when you could get a degree that will lead to an actual job? For most people, probably not. I think it's a great second major, but it should only be your only major if you're absolutely certain you want to get a PhD and become an academic philosopher, but good luck since there are only maybe a few thousand people in the world able to do that.
