optoprep

Hello! I need some advice.. so I finished KMK almost twice now, and i've been doing alot of optoprep. I finished all the practice questions, and now im on the timed exams. I've been doing half exams, but i keep getting 50-60% on them!! it's really frustrating. is this a cause for concern? i know...

I got 262F as my score, and I dont know what that means. I want to know how far I was from passing. Optics i scored in the 63 percentile, so that was my weak point. I want to retake it in August 2019. I am planning on taking the KMK signature summer course. if anyone has taking this course...
