Focus on the present and the future rather than dwelling on past results. Set clear, achievable goals for your JEE preparation and create a structured study plan. Break your study sessions into manageable chunks and take regular breaks to avoid burnout. Seek support from teachers, friends, or mentors, and practice mindfulness or stress-relief techniques like meditation. Remember, your past performance doesn't define your future success.
