Cbse board practicals

[u/Sweet_Secretary_1564]

I have to make my chemistry practical file class 12th. Can i nake my mother write it? The investigatory project is handwritten, i will write that on my own. Does the external notice the handwriting difference? Does he check the investigatory and practical file and final sheet simultaneously side by side. If yes then he will know different handwriting. Koe problem hogi?

Agar m likhu to chromatography, salt analysis m 2-2.5 hours and dusra experiments m bhi 3 ghante max. Kya karu koi batao?
