I would say go for it if you have no experience. Stick it out and in a few months you can tutor kids for £10-£15 an hour, maybe even £20. When you have experience and if you can get positive feedback you’ll find it A LOT easier to get students/parents wanting you to tutor them/their kids.
If you’re currently tutoring privately, stick with that. But most people will struggle to find people when they start out, if you’ve got someone focus on getting them the best grade so you can get positive feedback and then hopefully more opportunities
