Student Grading System

This is a simple Python project based on Cisco Python Essentials 1 (Module 3).

What it does:

1. Takes the student's name and marks as input.
2. Checks the marks out of 30.
3. Assigns a Grade (A+, A, B, C) and Rank based on marks.
4. Handles marks over 30 by stopping the program.
5. Asks the user if they want to continue or stop.

How to use:

• Run the script.
• Enter the name and marks (0-30).
• Type 'yes' to add another student or 'no' to exit.
