That all depends on where your numbers fall... Double tapped below both 25ths or above both 75ths that is true... Most everyone else will be waiting until January or later.
@alexandergreene93 That's how you measure the difficulty of an item in metrics, the percentage of people who get it right vs. the percentage of people who get it wrong. But you're right I'm banking on 7sagers being a reliable sample though
It depends on your diagnostic score and your target score. Without knowing those numbers, I would say you probably don't have enough time to study before the December exam. You should take your time and get the best LSAT score you can.
