  • Focus on logical reasoning techniques to solve direction-related problems.
  • Breakdown of common directional movements in terms of left and right turns, helping students to articulate direction changes more efficiently.
  • Practice examples from hypothetical and real-life scenarios, including competitive exam questions.
