How do I get back into math?

Brilliant.org

I'm here to second brilliant.org! The free community problems kept me interested while I was teaching high school and kept me sharp enough to be prepared for graduate school two years after graduating undergrad. The problems tell you if you're right/wrong, and you can post solutions to get feedback and/or read others' solutions.

Coursera

Just to echo some of the coursewarez recommended below I would suggest checking out EDX.org and coursera.org both of which run math courses at a variety of levels and you can audit them for free. Ofc there are more first year courses than second year, etc.
