Please help with any suggestions..

I graduated nursing school 2010 and never got the chance to take my nclex. My parents were both ill back home in the islands and I had to uproot my three children and move back to the islands to take care of them and the fact they lost everything from the tsunami. I stayed to make sure everything was in order. It took two years and now I'm back in the U.S to try and pick up where I left off. I just wanted to know if there was any suggestions out there about what refresher classes or courses I should take to prepare for the nclex.
