+# Day 6: Lists & Tuples
+
+## What You'll Learn:
+- List creation and indexing
+- Essential list methods (append, remove, sort)
+- Tuple creation and unpacking
+- Immutable vs mutable differences
+
+## Files:
+1. `list_methods.py` - Common list operations and methods
+2. `tuple_unpacking.py` - Working with tuples
+3. `list_operations.py` - Slicing and list manipulations
+
+## Exercises:
+1. Create a shopping cart program that:
+   - Allows adding/removing items
+   - Displays total items and unique items
+   - Calculates total price (items with prices)
+
+2. Build a student grade system using tuples that:
+   - Stores student records as (name, math_score, science_score)
+   - Unpacks tuples to calculate average scores
+   - Finds top performer in each subject
