Sims will improve when your basic concepts improve. Sims have a way of exposing weakness in basic concepts. The more you rely on Becker for basic concepts, the worse you will do on the sims because Becker often asks you to memorize at the exact moment that you need to learn something. On the exam, each sim is worth 10 points but you don’t need all 10 points to pass. No one gets 9 and very few get 8. You just can’t get zero or 1 point. The secret to passing is to average 4-7 points per sim, and how do you do that? By having a good understanding of basic concepts. Fortunately, i-75 is designed perfectly for that.
