Help! Question About Studying

Hey guys, how long do you guys spend when learning a section of LR. I feel like I take weeks learning a new topic before moving on to the next one. Any tips will help? Crying here at Starbucks while trying to study. I feel like I am taking way too long to understand something. Thanks!!

For example, to understand RRE questions, its taking me like 3 weeks and counting.
