As part of the UK government's advised stay-at-home regime, I've decided to stop teaching until further notice. I will of course retain on file any notes and credits for existing learners, and pick up where we left off. Don't worry, it's almost never the case that people fall backward in their learning after a break, even an extended one: that's the difference from book-learning.
I will be in touch before too long with some suggestions for off-line learning via this site. Stay safe !
