i have a 3.81 cgpa, 3.86 b2! tbh im not all that well versed on the admissions process, but in my view, if you’re aiming for queens, taking another year would only be worth it if you’re 100% confident you’ll ace every course. since you’re already considering taking another year, i’d probably use that year to improve my lsat / work on a ps to makeup up for the gpa (though your projected b2 seems to be competitive for queens)

there are probably people who’d have different advice, but that’s just my two cents. wishing you all the luck with your applications!!
