Chu Wei always makes sure to explain clearly the underlying concepts and fundamentals behind each topic, using various drawings, analogies and explanations until everyone in the class understands it.

Chu Wei's positive, motivational and amiable personality really pushed us to improve in our studies and made it less of a chore and more of a treat to attend his class. His tuition class was a one-stop shop for academic help, friendship, life advice and food.

Instead, Chu Wei explored my reasoning and patiently, yet skillfully, crafted a method to convince me of why my argument was invalid.This really made me realise that Chu Wei was not teaching for the sake of it, but truly because he wanted us to fully grasp and learn to love Math.
