A few months ago I graduated a 4-year physics degree/masters (MPhys) in the UK. I'll be starting my PhD soon and I was thinking of ways to supplement my income. I had the idea of possibly being a tutor to A-level and GCSE physics students to make a bit of extra cash. (By tutoring, I'm thinking of 1-on-1 sessions where some student pays me to just go through problems or explain concepts or whatever). The thing is, I have no teaching experience in the slightest, and I don't know whether I would make a good tutor. I certainly wouldn't want to waste any kid's time and money by being an incompetent tutor. I do hold a first class degree but is that enough? I have looked on a website where tutors advertise themselves, and they all seem to mention not only their first class degrees, but also a string of other professional achievements or experiences. Also, I only just barely scraped my first by the skin of my teeth, I certainly was not top of the class. I sort of feel like my degree was more deserving of 2.1 classification if I'm honest with myself. Do you think someone such as myself (23 years old, fresh out of undergraduate/masters year university, no experience of life outside the british education system) is well enough equipped to do this? Also, do I need to have any sort of license or anything to do this? Any teaching qualification? Or could I literally just post my phone number online or whatever, and hypothetically be tutoring someone by tomorrow? Also, please tell me if there's anything else you think I might have overlooked here. Thanks.
