UofT engineering - changing programs

Hello!

I was recently admitted to U of T's chemical engineering program. However, I'm not quite sure if I want to pursue chemical engineering and was thinking if it was possible to change into ECE or Track one before my first year starts.

I am aware that I can switch programs after first year, but I heard you need to maintain a 80% average and I was worried that I was not able to maintain such a high average (since U of T is known to be very difficult).

Thanks for reading
