Common Misconceptions & Examiner Traps

Common Misconception

Writing long, unstructured paragraphs without clear thematic headings or numbered points.

Scientific Reality & Correction

Structure answers with distinct headings, bullet points, and an opening definition followed by concrete examples.

Common Misconception

Confusing related conceptual terms due to superficial memorization rather than deep conceptual understanding.

Scientific Reality & Correction

Create comparative summary tables highlighting exact operational differences, legal scopes, or functional distinctions.
