How would you compare the material that kaplan provides versus the real comlex?

I've heard that the material is more or less USMLE style material with added OPP subjects here and there...

If you've take the comlex and had the kaplan review course:
1.) What are some similarities between materials?
2.) What is different with the COMLEX and kaplan material?
3.) How should one focus on studying for the COMLEX?

thanks!!

I'd like to know if COMLEX Qbank is indicative of the breakdown of subjects on the COMLEX...the majority of my questions (after 850) have been musculoskeletal (about 170 of them), and it's getting really f'ing annoying. I really hope the exam isn't that way.
