Evidence Act vs BSA - Humein Dhanata Hua Hai

Main ye samajh nahi sakta kya hai difference hai Jo Evidence Act mein section 59-60 ke madhyam se, aur BSA section 91-92 ke madhyam se explain kiya hai unhe. Dono concept kafi similar lagte hai, lekin main nahi samajh sakta unmein kya difference hai. Keh raha hai ki unmein difference hai bas "admissibility" se "relevancy" tak, par main kya difference samajh sakta hoon.

Jab unke cases likhne ke liye, main uthata hoon kahi isme se to isme to confusion hai aur jab mock test dekhne jata hoon to yehi sawal aata hai. Please help mujhe, yaar.
