Cleared Oracle Database 11g 1Z0-051 exam last weekend!
Scored 90%! (The passing score is 60%)
There were 64 questions in my actual 1Z0-051 test.
Many questions on SQL statements (Examine, Evaluate…etc.), Manipulating Data (Insert, Update, Delete), Using DDL Statements to Create and Manage Tables.
Also, please pay close attention to questions on Reporting Aggregated Data Using the Group Functions, Using Subqueries to Solve Queries, Creating Schema Objects, a little difficult!
I mainly learned the PassLeader 1Z0-051 dumps (http://www.passleader.com/1z0-051.html) (303q VCE and PDF), all questions were from it, and many wrong answers have been corrected in it, the most valid 1Z0-051 dumps! DO RECOMMEND!!
By the way, part of that 303q 1Z0-051 dumps are available here:
