How much time to complete Kaplan QTrainers?

I take the NCLEX-RN in 18 days. I have completed the Hurst Online Review (including the strategy questions) because I knew I needed additional content review and I feel it has helped a lot. I haven't taken any of the Hurst Q-Review tests yet. (I'm also working through LaCharity.)

I was planning to purchase Kaplan On Demand as well so I could access the Question Trainers and get a better idea of what kind of shape I'm in going into the exam, but now I feel like time is running short.

Would it make more sense at this point to (a) review my Hurst content, do the 6 Q-Reviews, and use some of the other sources of questions I have (Saunders CD, Kaplan CD, questions from a few other sources), or (b) would it be better to focus on taking the Kaplan QTrainers so I can get some scores predicting how I'll do (obviously this would also be a way to get used to doing lots of questions at once)?

I'd planned to do the QTrainers a bit earlier but didn't finish Hurst until now. I feel like time is running short and want to make the best use of the time I have left to study. I believe Hurst when they say focusing on content will help you get more questions right, but I think I might feel nervous going into the exam without the peace of mind that predictor scores might provide.

(Don't factor money into your response as I just want to know what would be the best plan moving forward if money wasn't a consideration...I'm prepared to pay for Kaplan On Demand if it will help me pass.)

Thanks for any insights you can provide.
