I am a first year student and what I will tell you is that covid won't change the outcome. Yes, maybe more people will get in with classes being online, for example, math faculty and CS took double what they usually do this year. This was stated by one of my former computer science professors. But to lay it out to you, you still need to be on top of your game in high school with marks. They may look at your EC's, actually, they will. They will see what you hav e done before this pandemic started. And they will still evaluate everything else on your AIF. As long as you have a good AIF prior to covid, and have good grades, then do not stress too much.
