Noraa confidence is key, even if you're unsure if you'll get in, on the day just go in telling yourself something like "i will do my best and get in" or "i have worked hard enough so i shouldn't worry." a few of my friends last year were crazy smart but on the day they got so nervous and absolutely flunked the test, while i know a guy who was literally the definition of average, 40s and 50s in his jac mocks getting lowest and lower sometimes but he did considerably well and got a PD to schs all because i remember him telling me that he wasn't scared at all, he figured he had nothing to lose and so he just went in and did his best. so dont overthink it, just be confident in yourself and your abilities and you will get in. trust
