Ask HN: Where can I deliberately practice math online?
I am no longer in college. The highest level of math I have taken is Calc 1. I have also take Discrete Math.
I'd like to improve my math skills and exercise my mind by practicing math problems. I don't have an interest taking a full course right now. I think practicing 30 minutes a day would do me some good in the long run.
