I took the exam a few years ago and my mother passed away in the middle of studying (I should have asked for a deferral).
Ethics and Standards came easy for me. Be sure to read all the vignettes and practice all the questions you can. Right now Schwesser is giving away their QBank and Video Series for free (check recent articles for code) so definitely take advantage of that.
There is also an article somewhere I believe on the order of subjects you should do. I have heard several places that it is best to leave Ethics to the last part.
