    Wrote my CIW Database Design Specialist 1D0-541 exam few days ago and passed with 92%! About 5 new questions, but not difficult at all. Total 50 questions, many questions on Normalization and Database Design/Structured Query Language (SQL), and DBMS/DDL/DML/DCL are still the most important objectives of the exam. BTW, the passing score now is 75%, and I learned all questions from passleader 1D0-541 dumps (http://www.passleader.com/1d0-541.html)
