IIS Aid

I use SQL very few time and always tried to avoid using it. I use it but only the basics I haven't really used SQL in several years. I got lazy and used the wizard on the application. I was in deep despair after having scratched in my very first test for OCP certification. I'm week on Pl/SQL programming. I'm seeking opinion regarding training courses, practice test, books etc needed to pass the exam. I have simulation kit for exam 1Z0-147 and fact and study guide attached with questions helping me. And all it in 70% discount, its just a good deal more than 280 questions and 80 study notes. Oracle Press (Osborne/McGraw-Hill) and Oracle press free downloads are mind blowing material and free of cost, OOfs database is very confusing and to relate each table, generating query, Basic Oracle Net Architecture, Basic Oracle Net Services Client-Side Configuration, Backup and Recovery Overview cleared from this stuff.
