The Self-paced training does not include direct access to instructors. Those who need interaction with an instructor should purchase Instructor-led training classes, such as Anypoint Platform Development: Fundamentals. If you have questions during the Self-paced training, check the forums to see if your question has already been answered or to post your new question. The MuleSoft Community forums are extremely active and well monitored and provide the crowdsourcing scale to help thousands of students.
