Pros
Once in a while you make a difference in a kids life. But very rarely.
Cons
Pay is terrible. If you are doing this in addition to your job you are earning about minimum wage minus your marginal rate, so less than $9 an hour. You only get paid when you are in a session if you do on demand. There aren't enough hours you can book, which are hours you try to select where you are paid to sit there with or without a person. This is by design, they minimize your guaranteed paid hours, and don't pay tutors enough for being on demand. Keep in mind parents are being charged $40 an hour and you are coming away with minimum wage. If you are doing this for a full time job good luck. You are far better stocking shelves at Walmart and try teach some of the teenage kids while you fill the shelf. Many of the kids are so far behind and so low in ability you will tear your hair out. High school kids trying to "complete the square" who don't know how to subtract negative numbers. I started off tutoring a lot but the frustration of super low ability kids and getting terrible pay will drive you crazy.
