I just passed my OCAJP SE 7 with 80%. Not a great score though!! I have been seeking for this since long. I went off to my village for peaceful preparation. Been familiar to java it wasn't much tough for me to bring it under belt. Since this was my maiden certification experience, I would share my pathway here.
1] Mala Gupta Written :
"OCA Java SE 7 Programmer I Certification Guide" is a great book to prepare for this exam. This book brings concepts clean and to the ground for beginners. Covers Exception Handling more elaborately. I liked classic front cover posters of all Mala Gupta books.
2] K&B Written :
"OCA/OCP Java SE 7 Programmer I & II Study Guide" is another amazing book covers both OCA and OCP exams. precisely lists out the exam objectives & their sequence and fun way of injecting the things is beyond perfect. Their suggestion to make flash cards served well in terms of last hour overlook before exam.
3] Java API Doc :
Needless to say anything about Java API Doc, helped me a lot.
4] Oracle Study :
Many thanks to the developers of Oraclestudy, its a worth product. Also I would thank myself for being part of this forum where I came to know about Oraclestudy. Nobody would like to appear on real exam without going through mock tests & when it comes Oraclestudy, it brings even more on the table. Being well known to all it actually toughens up the things and makes you short on time. At the beginning I was cared about the "real exam's unindented code snippet pattern"(somebody told me about that) which made me think about Oraclestudy should contain that feature to make the code snippet unindented. Thankfully it was not the case with real exam.
