Could y’all do me a favour.
Tutoring a friend’s daughter recently has reminded me that I love teaching maths. I’m looking to take on a few students to tutor this year (KS3 or 4)
Please share my details with anyone who might be interested.

Born #OnThisDay in 1887 was Indian mathematician Srinivasa Ramanujan. Despite having almost no training in mathematics, he is regarded as one of the greatest mathematicians of all time. He became one of the youngest Fellows in the Royal Society's history when he was elected in 1918 at the age of 31.
