📋 How to Calculate Your Grade

Problem: You scored 87 points out of 100 possible points on your math test. What's your grade?
Step 1: Divide points earned by total points
87 ÷ 100 = 0.87

Step 2: Convert to percentage
0.87 × 100 = 87%

Step 3: Find letter grade
87% = B+ (Excellent work!)
Your Grade: 87% (B+) - Great job! You're above average!

📝 Test Score Percentage

Problem: On a 25-question quiz, you got 19 questions correct. What's your percentage?
Method: Correct ÷ Total × 100
19 ÷ 25 = 0.76
0.76 × 100 = 76%

Study Tip: You missed 6 questions (25 - 19 = 6)
Focus on reviewing those topics!
Test Score: 76% (C+) - Room for improvement, but you're passing!

🛍️ Real-World Percentage Problems

Problem: A video game costs $60, but it's 25% off. How much do you save?
Formula: Percentage × Original Price
25% of $60 = ?
0.25 × $60 = $15

Final Price: $60 - $15 = $45
You save $15! The game now costs $45.

📈 Understanding GPA Impact

Scenario: Your current GPA is 3.2 with 30 credits. You're taking a 3-credit class and expect a 3.7 grade.
Current quality points: 3.2 × 30 = 96
New course points: 3.7 × 3 = 11.1
Total points: 96 + 11.1 = 107.1
Total credits: 30 + 3 = 33
New GPA: 107.1 ÷ 33 = 3.25
New GPA: 3.25 (+0.05 improvement) - Good progress!
