I guess it doesn't really matter. I'm also scoring 70+ in Rx, but I don't know if I should trust that. Along with Rx 2 blocks I'm also doing 2 blocks of UW each day, which is showing me around 60-70s. lol... But hopefully, since its my second time I will benefit a lot more by learning what I didn't last time. 🙂 The good thing is I don't remember the UW questions' answers, but I do remember the concept as I didn't memorize the UW questions, but focused on learning the concepts in it. The only thing that's weird is that I'm running short on time in Rx, but not in UW...
Thanks guys.. Good luck~
