+# Exercise: Student Grades
+
+## Concept Focus
+- Functions
+- Conditional Statements
+- Data Manipulation
+
+## Time Requirement
+20-25 minutes
+
+## Difficulty Level
+Medium
+
+## Problem Statement
+Write a Python program that takes the following inputs:
+- Student name
+- Number of subjects (integer)
+- Scores for each subject (list of integers)
+
+The program should then calculate and display the student's average score, as well as their grade based on the following scale:
+- 90-100: A
+- 80-89: B
+- 70-79: C
+- 60-69: D
+- Below 60: F
+
+## Example Inputs and Expected Outputs
+### Input
+John Doe, 3, [85, 90, 78]
+### Output
+Student Name: John Doe  
+Average Score: 82.67  
+Grade: B
+
+### Input
+Jane Smith, 2, [92, 95]
+### Output
+Student Name: Jane Smith  
+Average Score: 93.5  
+Grade: A
+
+## Instructions
+1. Write a Python program that takes the student name, number of subjects, and scores as input.
+2. Use functions to calculate the average score and determine the grade based on the provided scale.
+3. Print out the student's name, average score, and grade.
+
+## Hint
+- You can use the `sum()` function to calculate the total score, and then divide by the number of subjects to get the average score.
