It is also connected with Salesforce Certified Platform Developer II. If this is the credential you are working toward, the 240 practice questions at Actual4Cert map directly to its objectives.
The Salesforce Certified Platform Developer exam includes 60-65 questions, and you have 105 minutes to complete them. Divide the time limit by the question count and you get a tight average pace per item, so train yourself to flag time-consuming questions and return to them later instead of getting stuck. Before test day, run at least one full timed session in the Actual4Cert test engine under the same limits — the clock should never surprise you.
The passing score for Salesforce Certified Platform Developer is 68%, and the official registration fee is US$200. A failed attempt means paying that fee in full again, so your preparation budget deserves the same attention as your study plan.
