IPC aur BNS ka maze kuch samjhne mei

Mujhe to ye samajhne mei kafi dikkat ho rahi hai ki IPC aur BNS mein ACTUALLY kya fark hai. Mainne so far sir ke lectures dekh liye hain, aur Ratanlal Sharma ki book padhi hai, lekin mere brain mein to ye sab kuch jhund jhund hai. Mera problem yeh hai ki IPC ka content BSN ka samna nahi karta, aur BSN mein IPC ki references bhi bahut kam hain. Sir ne kaha hai ki hamein IPC aur BNS dono ka concept clear karna hoga, lekin mujhe to ye samajhne mei kafi mushkil laga raha hai. Kya aap koi book, notes ya video suna hain jo aisa kuch bataye jisse hamein clarity mile?
