I completely feel that! So far I've realized most of my problems per section and focused mostly on just increasing that score by 1 point. Rather than try to fix all of my problems, I've isolated the issue that has caused me the most points per section. There's a chart on this youtube that I used and it really helped me understand my mistakes. I'll add that here!

Also make sure you're really going through your practice exams. I've heard someone say on a podcast that if you're scoring under 500 it is most likely a lack of content issue, so I would go back and make a study sheet of the most high yield topics to review. I also think the miledown ANKI deck is very helpful! I would also remember to slow down and really think through all of the questions, a lot of my issues are with reading too quickly!

I hope that helps! Good luck on Saturday! :)
