  • Answer writing सबसे neglected और सबसे important skill है
  • GS I-IV में current affairs + static knowledge का integration ज़रूरी है
  • Optional subject selection carefully करें - यह game changer है
  • Interview के लिए personality development Mains के साथ-साथ शुरू करें
  • UPSC Complete Guide में Prelims strategy भी available है
