Crafted with EdrawMax, this template maps the user operation flow of an online course platform. Starting with "start," users first encounter the course page. Those without an account register, filling in details, while existing users log in by entering email and password. After credential verification, users access the course page, enter a valid join code to participate, complete quizzes, view scores, and adjust profile settings. Finally, a decision on logging out concludes the process. This visual guide is ideal for developers building online learning systems or educators organizing course access, clearly presenting user interaction steps from account setup to course engagement and logout.
