The credential is also connected with related certifications such as Oracle MySQL Certified Professional, so it can serve as a solid step in a broader certification path.
The 1Z1-921 exam has 52-78 questions in total and must be completed within 90 minutes. That leaves only a narrow time budget per item, so train yourself to flag a difficult question, move on, and circle back later instead of getting stuck. A week or two before your test date, run at least one full timed mock exam in the PracticeMaterial desktop or online test engine under the same 90 minutes limit, and repeat until you can finish with a few minutes left for review.
The passing score for the 1Z1-921 exam is 65%, and the official registration fee is USD $245.
