Beginner’s Guide to What-If Analysis with Practical Example

Learn how to predict your exam score changes using hypothetical scenarios!

---

Key Terms

1. Correct Answers: Questions you answer right (+1 mark each).

2. Wrong Answers: Questions you answer wrong (–0.25 marks each, assuming ¼ negative marking).

3. Unattempted: Questions you leave blank (no marks).

4. What-If Analysis: Testing how changes (like attempting more questions) affect your score.

Example Scenario

Let’s break down the given example step-by-step:

Original Situation

• Total Questions: 100

• Correct: 60 ➔ +60 marks

• Wrong: 20 ➔ 20 × (-0.25) = -5 marks

• Unattempted: 100 – (60 + 20) = 20

Current Score:

60 (correct) – 5 (wrong) = 55

---

What-If Scenario

You attempt 10 more questions:

• New Correct: 60 + 7 = 67

• New Wrong: 20 + 3 = 23

• New Unattempted: 100 – (67 + 23) = 10

New Score Calculation:

1. Marks from correct: 67 × 1 = +67

2. Deductions from wrong: 23 × 0.25 = 5.75

3. Final Score: 67 – 5.75 = 61.25

Net Gain: 61.25 – 55 = +6.25

Step-by-Step Guide

1. Start with your current performance:

   • Total questions, correct, and wrong answers.

2. 
   

3. Add hypothetical attempts:

   • How many more questions will you try?

   • Estimate how many you’ll get right/wrong.

4. 
   

5. Calculate new totals:

   • New Correct = Original Correct + Additional Correct

   • New Wrong = Original Wrong + Additional Wrong

6. 
   

7. Check for errors:

   • Ensure New Correct + New Wrong ≤ Total Questions.

8. Compute the new score:

   • Use formula:

     
     

     Score = (New Correct × 1) – (New Wrong × 0.25)

Visual Summary

Metric	Original	What-If	Change

Wrong Answers	20	23	+3
Unattempted	20	10	–10
Score	55	61.25	+6.25

Why This Matters

1. Risk vs Reward:

   • Attempting 10 more questions gave you +6.25 marks, but required risking 3 wrong answers.

   • Is this worth it? Depends on your confidence in those extra 10 questions.

2. 
   

3. Strategy Building:

   • Use this method to decide:

     • How many questions to attempt

     • How many wrong answers you can afford

4. 
   

5. Avoid Over-Attempting:

   • If your "What-If" totals exceed the exam’s total questions, the calculator will warn you!
