The actual certification exam was no different than the various attempts i made on the online practice tests on dbexam.com. Right from the Oracle Java SE 11 Developer Syllabus syllabus of the exam to the duration offered to complete the 1Z0-819 questions in the mock tests, everything was similar. This made me prepare for the actual exam without giving me the horrors of the same. I prepared gradually for Oracle Java SE 11 Developer Certification in 2 months and climbed the success ladder.
