Introduction

  • Practice improves speed and comprehension

Key Techniques for Exam Preparation

  • Bold Scanning: Identifying key terms in a question
  • Deductive Reasoning: Remove obvious wrong answers to increase odds
  • Three Wave Method: Tackle questions you know first, mark uncertain questions, and revisit them later
  • Avoid timing yourself initially
    • Focus on understanding rather than speed
    • Time practice should be reserved for last two weeks before the exam
