Prince George, Canada
I tutor high school mathematics and I'm working on rekindling my lost calculus and linear algebra skills.
When I was in school, I had plenty of time, and I would save all my math homework for the weekend before the midterm and then engage in a weekend math marathon.
No I'm all growed up with responsibilities. I have less time, but I get up at 4:00 and study before I go to work.
I recommend the slow and steady approach over the marathon approach, having tried both.
I'm also working on Biblical Hebrew, Greek and Esperanto.
