Hello aspirant..
Firstly complete all your practical file, and maintain a record which is good with first impression.
Second - prepare two types of titration 1)  mohrs salt 2) oxalic acid.
Third- learn complete salt analysis.
Third- prepare for viva very well with confidence. In viva be confident they will ask 2 or 3 question maximum which I think you can handle it.
I can give you an idea about CBSE exam. The test is mainly divided into 3 parts. You have one hour for each. However you can do mainly ever is left at the end. First you need to do the titration and write down the result in the answer sheet provided followed by salt analysis and organic analysis. After completing each task you have need to show your observation.
And no more changes compared to other state syllabus board examination. ALL THE BEST hope you will do better and you can do better when you believe in yourself. Thank you....
