I considered doing this myself but didn't for a few reasons. I have tutored math (college level) for sometime now and it has proven to be quite lucrative at times. I don't do it much anymore but in college and my early-career time frame (when I usually needed money) it was great. The primary reason tutoring math is better than comp sci (IMO) is the following: In all levels of schooling and in practically every domain, math is required whether you like it or not. Computer science is not. I chose upper level math because of the types of rates I could charge. It's very common to get clients who have high paying jobs who also need tutoring in math. For example, a nurse who wants to sit for the GRE to get into grad school will probably need help in math because math wasn't a primary focus area when he went to college 3 years ago. That same nurse probably makes a lot of money and can pay you well (Especially if you show that you made an extremely high score on the math section of the GRE.) Computer Science isn't required in most walks of life so so you'll automatically reduce your clientele to mostly just students. Furthermore, they'll be the smartest of the students (engineers, comp scientists, physicists, etc..) so there won't be many to chose from. These kids didn't go into these fields cause they're bad at learning from their teachers... They also are reasonably savvy at looking up a free tutorial online. Worst part of this is the fact that most of that group will be broke. If you're looking to make money at this, you need a steady stream of people who can pay. This demographic will not result in that (my experience only. yours could be different). This is not to say that you should tutor math. It's to say that you shouldn't tutor comp sci. All this changes if you're doing this for fun/volunteering. I mostly just tutor younger friends/family members now for free. There are definitely worse ways you could spend your time.
