Format

The course is designed to provide maximum flexibility while ensuring participants receive continuous support throughout the program.

Self-paced video lectures – All lectures are pre-recorded, allowing you to learn at your own pace, at a time that's convenient for you, and revisit the material whenever needed. New lectures are released weekly, with one new lesson becoming available each week. Every lecture is accompanied by a practical hands-on assignment to help you apply the concepts covered in the lesson.
Live Q&A sessions – Interactive live meetings are held every two weeks, giving you the opportunity to ask questions about the previous two lectures, review assignments with the instructors, discuss key concepts, and receive guidance on any challenges you encounter.
Progress assessments – The course includes three assessments to help you track your progress:
- Prerequisite Assessment – Evaluate your readiness and identify any knowledge gaps before the course begins.
- Midterm Assessment – Covers Lessons 1–4 and helps you measure your progress while encouraging you to catch up if needed.
- Final Assessment – Evaluates your overall understanding of the course material and is required to earn the Course Completion Certificate.
Community support – Participants will have access to a dedicated community group for course announcements, discussions, asking questions, and receiving timely support with homework and technical issues throughout the course.
