• The top-scorer in CELS 191 was awarded a
prize, and sent the following email to teaching
staff
“PeerWise is a very good learning tool, especially for
revision after a lecture. I find that if I can explain the
concept, then I have grasped the ideas of the lecture,
and if there is something I am struggling to grasp
someone will have posted a question which once I
have worked my way through, makes the concept
clearer. So I am very grateful for the resource.”
