Question 1 Draw an activity Diagram in draw.io and screenshot it for me. Scenario (please alert is in Draw.io) Each semester the student will need to register the subjects that they need to take. The student needs to login to the system by inputting their student ID and password. The system uses that student ID to retrieve the intake of the student and based on their study plan, the system will display a list of subjects the student can register. The student can now click on the subject they wish to register. When the student is satisfied with the subjects chosen, the student will click the register button. The student may register more than 1 subject but the total credit hours for the subjects cannot exceed 20 credit hours. If it exceeds, the student has to choose all over again the subjects to register. If successfully registered, the student’s status in the system becomes “Active – Registered”. If the student does not register any subject for the semester, the status is…
