I haven’t been through uni application yet so I don’t know but I’d say try focus on other things because worrying about it won’t change the decision that they make so you might as well try and think less about it and be productive to take your mind of it. What’s meant to be will be ..if UCL is the right place for you that’s where you’re going . Try not to stress
You'll do just fine, yeah?Whatever the outcome, you'll be glad you got to appreciate the suspence. And the decision they agree on will mean more now that you are actively waiting for it. Best of luck, fingers crossed
