I'm in the second week of MITx 6.002... I feel so fortunate that there is so much free material out there.

I'm 40, and in the last 9 moths or so I've been able to get back into doing calculus well enough that I can follow these kinds of classes.

That fact has been making the next 40 years or whatever I have a lot more palatable to know that if I want I can enjoy working with this stuff.
