The IBM Cloud Professional Developer v6 is the official IBM exam that leads to the IBM Cloud Professional Developer v6 certification at the Professional level. Passing it validates your skills against IBM standards and proves your qualification to current and future employers.

The C1000-166 exam has 65 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 ExamPrepAway 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 C1000-166 exam is 40/65, and the official registration fee is $200 USD. Keep in mind that a failed attempt is not discounted — retaking the exam means paying the full fee again — so it is wise not to book your seat until your practice scores sit comfortably above the passing mark. Working through the 181 questions at ExamPrepAway in timed mode is a reliable way to judge when you are truly ready.
