I am sharing my Paper 2 Public Administration strategy. If any doubt you can always ping me on ForumIAS or Telegram or here only.
Books and coaching notes-
1. R Aribam book ( a very crisp and good source. It’s all MOHANTY sir notes but better organized)
2. Arora and Goyal book ( another good book but some topics not much relevant – choose wisely)
3. Selective topic reading of Fadia and Fadia Indian Admin book if you are pure fresher in the subject
4. 2nd ARC original once ( Drinking like juice) + Pawan sir summary of same (to learn linkages)
5. Kiran sir notes of Vajiram / Pawan sir notes ( read anyone – if possible both)
