MuleSoft Developer 2 passing score and exam format

The MuleSoft Developer 2 passing score is 70%, the same bar as every other MuleSoft track. This quick-facts guide covers the MCD Level 2 exam format end to end: the number of questions, the Developer I prerequisite, the retake policy, and what the scored Salesforce Certified MuleSoft Developer II exam (Mule-Dev-301) actually measures. A few figures - the exam duration and the registration fee - are not consistently confirmed on Salesforce's current pages, so they are flagged below as figures to verify on the official exam page before you rely on them. Every figure here is composed from a single source so it matches the Developer II certification hub exactly.

What the passing score means in practice

The Developer II exam is graded pass/fail against a fixed 70% threshold. With 60 scored questions, that works out to roughly 42 correct answers needed to pass, though Salesforce does not publish a per-question weighting and reserves the right to scale items.

There is no partial credit and no penalty for guessing, so leave nothing blank. The result is reported as pass or fail immediately after you submit; you do not receive a numeric score breakdown by topic, only a high-level indication of stronger and weaker areas.

Exam format, question types, and duration

Developer II is a proctored exam of 60 scored multiple-choice and multiple-select questions, generally listed at 120 minutes - confirm the current time limit on the official exam page, as Salesforce's published pages are not always consistent on this. You can take it at a test centre or online with a remote proctor. 60 scored multiple-choice / multiple-select questions; proctored onsite or online.

Compared with Developer I, the Level 2 exam leans harder into applied scenarios: error handling strategies, transactions, the batch job phases, securing APIs, performance tuning, custom policies, and deploying and monitoring Mule applications. Expect questions that hand you a flow or a requirement and ask which approach is correct, rather than asking you to recall a single fact.

Prerequisite and retake policy

Developer II has a hard prerequisite: Requires an active Salesforce Certified MuleSoft Developer I (Developer) credential. You cannot register for Developer II without an active Developer I credential, so plan the order of your certifications around that.

On retakes: Retake fee $100 USD per attempt. If you do not pass, you can schedule another attempt after the published waiting period. The full path and per-attempt fees are covered in our cross-track cost guide.
