I'm an A'level chemistry tutor and I employ an A'level physics tutor as part of my business. However, as we're not local to Harrow, all tuition is done online via Skype (or Zoom) and interactive online whiteboard. I have only 1-2 slots left for the coming academic year because I'm almost fully booked and get booked up early. My physics tutor has a few more slots left because she is not a full time tutor (full time teacher though).
PM me for info if you'd like me to expand further on any points :-)
