Hello, parksy. Thank you for completing the course. This content can feel a bit challenging when you first encounter it. Rather than trying to understand everything perfectly at once, this course is structured so that it becomes much easier to grasp once you've familiarized yourself with the overall flow and watch it again. If you take the time to review it once more without pressure, the parts you might have missed before will become much clearer. If you have any questions, please feel free to leave them anytime! Thank you.
