Draw a System Sequence Diagram $($SSD$)$ to illustrate the interactions between the actors and the system for the following scenario:

A student logs into the platform and browses available courses. The system displays a list of courses, and the student selects a course to register. The system prompts the student to confirm registration and enter payment details. After submission, the system validates the entered information. If validation fails, the system notifies the student, allowing them to correct the details $($looping back to the payment details entry step$).$ Upon successful validation, the system processes the payment and confirms the course registration. The system checks if the student wants to register for more courses, iterating back to the course selection step. If no more courses are desired, the system generates a registration confirmation for the student.
