• Section A (3-point): 15-20 minutes
• Section B (4-point): 25-30 minutes
• Section C (5-point): 25-30 minutes
• Review: 5-10 minutes (if time allows)
🎨 Visual Problem Solving
Draw Your Way to Success:
• Sketch diagrams for geometric problems
• Use visual organizers for word problems
• Draw patterns to identify sequences
• Create charts for comparison problems
❌ Elimination Technique
Smart Guessing Strategy:
1. Read question carefully
2. Eliminate obviously wrong answers
3. Use logical reasoning on remaining options
4. Make educated guess from narrowed choices
Remember: No penalty for wrong answers!
🔄 Check and Verify
Quality Control Process:
• Substitute answers back into problems
• Use estimation to check reasonableness
• Look for common mistake patterns
• Double-check calculation steps
🧩 Pattern Recognition Mastery
Systematic Pattern Analysis:
• Look for repetition and cycles
• Check mathematical relationships
• Identify growth patterns (add, multiply)
• Consider position-based patterns
🎯 The “Skip and Return” Strategy
When encountering a difficult problem:
1. Don’t panic – mark the question and move on
2. Continue with easier problems to maintain momentum
3. Return with fresh perspective and remaining time
4. Apply elimination technique if solution isn’t clear
This strategy prevents time waste and reduces anxiety during the test.
Expert Tips & Secret Hacks
🧮 Mental Math Shortcuts
Multiplication by 9 hack: Multiply by 10, then subtract the original number
Example: 9 × 7 = (10 × 7) – 7 = 70 – 7 = 63
Doubling and halving: 16 × 25 = (16 ÷ 2) × (25 × 2) = 8 × 50 = 400
📖 Reading Comprehension Tricks
Highlight key numbers and operation words (total, difference, each, etc.)
Rewrite the question in your own words to ensure understanding
Identify what’s given and what needs to be found
🔍 Pattern Recognition Hacks
Look for differences: What changes between consecutive terms?
Check positions: Is there a relationship to the position number?
Test multiple examples: Verify your pattern with several cases
📐 Geometry Visualization
Use your finger to trace shapes and paths on diagrams
Rotate the paper to see shapes from different angles
Count systematically when determining quantities in complex figures
⏰ Time-Saving Techniques
