Oh wow, I remember hearing about this challenge on Daily Planet when I was still in elementary school. It's super cool seeing a follow up, it brought back a hidden memory.
Although I agree with the sentiment, the Ontario university system doesn't actually work that way. For example for Software Engineering at Waterloo, the admission average is calculated using the five required courses plus whatever your highest course is excluding the former[0].
In practice, I believe every single Ontario university program lists English one of the required courses so it will always be included in your top six average.
Super cool demo btw
