Tips for Getting the Most Out Of Learn Mode

  1. Actively Read the “Why” (Don’t Just Look at “Right/Wrong”) 
    • When you receive immediate feedback, the most valuable part is not whether you got it right, but why the correct answer is correct.
  2. Treat Mistakes as Immediate Lessons
    • In Learn Mode, a mistake is not a failure; it is an immediate opportunity to correct a misconception.
  3. Actively Challenge the Distractors
    • Don’t just look for the correct answer; look at the incorrect options (distractors) and understand why they are incorrect.
  4. Re-engage with Content Instantly
    • If the feedback reveals a gap in your knowledge, don’t just click “Next.” Take advantage of the immediacy to look back at the training material while the question is still fresh in your mind. 
  5. Take Notes on “Corrective Feedback”
    • Maintain a “mistake log” or note-taking area. When the quiz explains why your answer was wrong, jot down the correct rationale.
  6. Treat It as a “Study Session,” Not a “Test” 
    • Because you are getting the answers immediately, there is no need to feel anxious about getting it wrong.
