Key:
-
60% of exams test higher-order thinking (L3/L4).
-
Top-weighted topics: Angles (10%), Symbols (10%), Lines (8%).
Teaching Tips
-
Prioritize Hands-On Practice:
-
Use CAD tools (L4) for orthographic/pictorial drawings.
-
Reinforce line division (L3) with scale models.
-
-
Common Pitfalls:
-
Students often confuse 1st vs. 3rd angle projection (L2→L3).
-
Loci construction (L4) requires iterative practice.
-
-
Engagement Ideas:
-
Competitive sketching drills for symbols/lines.
-
Real-world case studies (e.g., bridge forces for L4).
