Last week I was approved in part 1 with 78% . Thank you to everyone for their help and valuable tips. I did a summary of everything you need to know and remember to pass on part 1 and can be downloaded here - http://fernandofranzini.files.wordpress.com/2012/07/ocmjea-jee5-1z0-864.pdf.
Now it is starting studies for parts 2 and 3.
I am available for any doubts!
