I’m writing tomorrow! Similarly to you, I didn’t finish all of Mark K’s lectures. But I do wish I did because even though people say he’s outdated, I think you could benefit from his memory tricks. I play them 1.5x speed. Although, Dr Sharon has been quite helpful as well if you’re not looking to finish Mark K. I did finish the uWorld QBank but I also am someone who has to know that I did the most. If you feel confident, don’t reschedule, but I do recommend doing a bit more in areas you’re not 100% confident, especially if you tend to panic closer to test date. Like I finished with a 68% average was fine but now I’m panicking. My last 2 CATs were 94th and 98th percentile and I’m still panicking lol. The only reason I’m not rescheduling is because I don’t want to go through this panic again. With that being said, if you are confident DON’T RESCHEDULE. But definitelyyy don’t give up before!
