I was failing maths at secondary 3. Through a friend, I knew about ms ang and signed up for the tuition classes. She goes through the overview of the lesson before she starts teaching and explains the steps clearly unlike teachers in schools that teaches us Methods but fails to explain how it came about. That pulled me from my failing grades to a b4. She teaches us the best shortcuts that are “right”. “right” as in all of them are acceptable in the GCE Olevel marking scheme. These shortcuts were our major stepping stones out of the b4 to b3 range to the a1 to a2 range.
And I emerged with an A1 for both maths for o levels.
