I have a masters degree in Aerospace Engineering, and I have worked as a Mechanical Engineer for Rolls-Royce. Today I work part-time as a voluntary and private Maths tutor. Its something I thoroughly enjoy doing. I also have several years teaching experience.
I spend around 10-15 minutes before every tutoring session planning the lesson. This way when I come to the tutoring session, I know exactly what I`ll be teaching on the day. It saves time.
