🧠 How BrainPulseIQ Calculates Your IQ

At BrainPulseIQ, we believe that intelligence is multi-dimensional, and testing should reflect that. Our IQ scoring system uses a combination of accuracy, question difficulty, and response time to estimate your cognitive ability with more nuance than traditional point-based tests.

✅ 1. Each Question Is Independently Scored

Each question is categorized by the type of intelligence it measures:

• Verbal Reasoning
• General Knowledge
• Mathematical Reasoning
• Logical Thinking
• Pattern Recognition
• Visual-Spatial Processing

🎯 2. Questions Have Assigned Difficulty Levels

Not all questions are created equal. Based on their category, questions are rated by difficulty:

• Easy (e.g., Verbal, General) – Weight: 1
• Medium (e.g., Math, Logic, Pattern) – Weight: 2
• Hard (e.g., Visual) – Weight: 3

⏱️ 3. Response Time Matters

We lightly factor in how quickly you answer questions:

• < 8 seconds per question: small bonus
• > 15 seconds per question: small penalty

🧮 4. The Final IQ Score Formula

We calculate your final score using a formula based on the normal IQ distribution:

IQ = 100 + ((Your Score - Average Score) × 15 / Standard Deviation)
      

- Average Score: 20
- Standard Deviation: 5
- Time Adjustment: ±5 IQ points
- Score Range: 60 to 160
