Salesforce Platform Developer I
Practice Exam
The Salesforce Platform Developer I certification is an intermediate Salesforce credential with no prerequisite. It is focused on developing custom applications on the Salesforce platform using Apex and Visualforce. The exam has 60 scored questions plus 5 unscored questions, a 105-minute time limit, and a 68% passing score. Its official outline covers 4 weighted sections, the largest being Process Automation and Logic at 28% of the exam.
Platform Developer I proves you can build custom applications with Apex, Lightning Web Components, and declarative tools. The exam is scenario-heavy — reading about Apex is not the same as recognizing the right governor-limit-safe pattern under time pressure.
