Am I ready?

After Studying for a few months for my CCNA I started taking the Boson test. After failing abysmally I really made an effort to read why I was wrong and why the correct answers were correct and after a few weeks I am averaging in the high 80s low 90s but despite my best effort I feel like I am memorizing the correct answers rather than actually learning. From what I read Boson is harder than the actual test but people said the same thing about the Network+ and Jason Dion's practice test and I feel like that was completely off. Did anybody else go through this? Let me know if I am overreacting.
