IPC vs BSN: Kitna confusion, bhai!!

Main to sochta hoon, IPC aur BSN (Bare Acts with Short Notes) mein kya difference hai bhai? Pehle IPC mein jo cases hai, wo toh BSN mein bhi hote hain lekin wahan ke short notes ke saath hi! Kya aap logon ne is problem ke saamne koi solution paya hai? Main to kai jagah par padha hoon ki BSN mein IPC cases detail mein milte hain, lekin fir bhi main samaj nahin sakta ki kya difference hai. Main to yeh soch raha hoon ki IPC main koi special cases hai jo ek saath na hain BSN mein?
