I had passed the exam "Introduction to Oracle9i: SQL 1Z0-007" in 2008. Long ago ! However now I want to pass the exam "Oracle Database 11g: Program with PL/SQL 1Z0-144". Now please check the link https://education.oracle.com/oracle-pl-sql-developer-certified-associate/trackp_162 . Can I go the "Step2 - Pass Exam" without passing any other exam from "Step 1" as I have completed 1ZO-007 with passing score 71%?
