Student Registration for a Course

Test the portal's "Student Registration" feature by simulating a student's course enrolment. Input sample data such as name, email, phone, state, city, referral code, and selected courses. Verify front-end validations like required fields, email and phone formats, and referral code checks. Upon submission, ensure data is correctly stored in the database (students and course_enrolments tables). Confirm success via a user message and optional email notification. Test edge cases like empty fields, invalid referral codes, and maximum course limits. Validate database integrity and session handling for smooth functionality.
