After reading selftestsoftware first 5 chapters, Sybex OCA book first 3 chapters: Architecture, DBCA, DB management reading is a breeze, within one week. Then scan through again backup and recovery very quickly, performance monitoring quickly. Locking one day finish detail read. Security and PL/SQL slow down a little bit but quick scan. All in all done all this in about a week.
