When I first started doing Kaplan I was scoring in the 50's too. About 3 weeks before my exam, I started doing more questions every day and my scores went up into the 60's and 70's even! Just practice, go over every single question's rationale, and I think that will help you. I did 100 questions the day before even though everyone said not to. However, for me, if I skipped a day of practice my scores ALWAYS went down. I passed with 75 questions, but I will just never know if doing those 100 questions the day before helped. All I know is that my NCLEX was just like Kaplan, font and everything. Good luck!!
