Tutoring usually brings $20-40 an hour, but you have to find your own students and have a place to meet with them, either in your home or theirs. Tutor.com finds the students for you, and you tutor in your own home online. Students range from 5 to ??? and the questions and sessions are varied. Tutor.com provides you with a mentor who helps you improve your approach, and flexibility: as a 24/7 operation, they are there when you are ready.
Pay is relatively low: $10-15/hour, and summer hours are hard to come by. Additionally, you are an independent contractor, which means paying your own SSI/SSDI and taxes.
