UBC Personal Profile

I'm trying to major in CS at UBC. I'm aiming for 95% core average on my necessary courses, which I think I can do. However, I feel overwhelmed about the personal profile that I have to do, and I just have this anxiety & impostor syndrome that I can't do it and one miss is going to severely drop my chances of getting in. Secondly, I know that I can't do the service student (literally doesn't exist in my school), nor become a lead of a club, and I seriously doubt I can secure some decent work exp. I don't know how much exactly that's going to hurt my personal profile, so please do tell me, assuming I do get the 95% average, what out of that action plan I will need to do in order to get in. I feel overwhelmed by the game jams that I have to do, because of the impostor syndrome I feel like I'm going to fumble miserably or not know what I'm doing. Finally, on top of the anxiety and impostor syndrome, I feel really directionless and unable to actually lock in, or what I think is locking in. Any advice?
