I am 53 and cramming while relearning linear algebra, statistics, and calculus, after a 30 year break from college, in preparation for my first semester at GA Tech's online MS CS program in the fall. I love this! But...before I check it out, I'm going to be surprised if it competes with the already-incredible free help i've gotten from chatgpt-3.5. Recently I asked it the following (where it made a mistake that confused me!), but i followed up w/ a question about it, and it corrected the mistake and re-answered the question, all with no wait at all, and free:

```Given a new 3x3 matrix A having columns (4,2,2), (-1,1,-1), and (6,6,8) and an eigenvalue of 2, help me find a basis for the corresponding eigenspace. Also, given that I is the 3x3 identity matrix, why does the equation (A - 2I)x = 0 having free variables make it obvious that 2 is indeed an eigenvalue.```

I'm still going to check out your site, and I do wish you well, but i'm curious how it will stack up against AI tutors.
