Exam Format
You will be able to take the exam from your own personal device using the Certiport Compass Broswer, or by going to a certified testing center to take it in-person.
The exam is 45 minutes in length, and contains 38 questions.
All questions will be written in the format of either multiple choice, drag and drop, dropdown, and ordering. Questions will assess your ability to answer basic questions about the JavaScript language, fill in missing code segments, interpret code output, and detect errors in code.
