Hi,
I've passed this year both the
OCAJP(88%) and OCPJP(73%). For each I've spent some weeks reading the Mala Gupta books as background lecture and then dedicated 5 days doing Enthuware mock exams (and re-reading the chapters in the book based on my missed questions). The Mala Gupta books are easy to read; the second one is still being finalized but it's good enough. The Enthuware tests are really a great preparation and a bit more difficult than the real exam.
Regards,
Fernando
