Chemistry Class 12th Practical File

In This Blog, I will share the All Chemistry Class 12th Practical files Including All Activities. As the CBSE ( CENTRAL BOARD OF SECONDARY EDUCATION) Examination is coming, we are Supposed to Submit Our Practical File To The school so that we can get Practical Marks. Here In this Blog, I had Shared My Class 12th Chemistry Practical File Pdf With You, and also you can Download It From Here.

CBSE Class 12 Chemistry Practical (Term 2) 2023: Marking Scheme

This Year the CBSE IS conducting class 12th exam twice a year in the form of term 1 and term 2, so the syllabus is splitted as per as the CBSE notification, Generally Cbse class 12th Chemistry Practical carries 30 marks including all Viva and activities but this year due to splitting of syllabus Term 1 practical carry 15 marks and term 2 carries 15 marks.
