Sorry for my English. I have been studying English for about 4-5 months. After about 4 weeks of rather intense preparation, I passed the Java SE 7 Programmer I(1Z0-803) exam today with 86% score :-).
I started preparing 1 month back studying Mala Gupta 1z0-803 book, enthuware software (http://enthuware.com/) and Java Language specification. I read the book, then did tests. Big thanks to the developers test Enthuware. They are very helpful. Exam passed by 86%. Part of the questions answered wrong, because I do not know the exact translation into the native language.
Now I am planning to prepare for the 1Z0-804 SE 7 Programmer exam and study English language.
