My apologies Negi, I didn't see the post where your correct answer was changed to 1.xxx Meters. That answer aligns with my own perfectly. Previous answers were in the 6ft/2m range.
2 years ago I had a chemistry tutor who conducted a lesson on MS for a poor classmate of mine. My tutor basically KSed my classmate throughout the entire night and kept asking him to do his homework (which he hadn't completed).
And my tutor's level was twice that of my classmate.
The Internet allows you to use endless resources during tutoring session. Distance makes the student do more self-study. There are no notes from the tutor to write off when working on the problem. During the pandemic, I'm on https://studymind.co.uk/a-level-maths-tutors/ I bought some courses for my son. He has a dream to become a good plastic surgeon.
You're GEM!
