Hello Priyasal,

The class 12 boards is one of the most important practical in your life.

As there will be an external coming totake your viva and also the final marks will be reflected directly in your boards.

theboard exam consist of 2 practicals which u have already done in class 12 ,and you have to perform these within a prescribed time(3hrs) and then finally an external will ask you question regarding your projects and viva which u performed and will give you his/her marks.

The total practical is of 30 marks and is quite crucial.

HELLO PRIYSAL,

ACCORDING TO YOUR QUESTION AS YOU HAVE ASKED THAT IN 12TH BOARD EXAMS WHAT IS THE MARKING SCHEME FOR BOARD PRACTICALS .

SO IN 12TH BOARD EXAMS THE PRACTICAL CARRY THE WEIGHTAGE OF 20 MARKS AND THE REMAINING 80 MARKS ARE FOR THE WRITTEN MARKS SO FOR SCIENCE STUDENTS THE PRACTICAL EXAM MARKS CARRIES A LOT OF IMPORTANCE AS IN EXAMS THE PRACTICALS ARE OF 30 MARKS OR OF 40 MARKS AND THE REMAINING MARKS ARE FOR THE WRITTEN EXAM .

Yes it will consider nothing to worry because if u done some little bit mistake then they will give good marks and if you done correctly all things then your full marks is definitely fixed so don't worry about it and this basic thing you should know about it any way I told you so don't worry about it and go ahead in your life

you have to do more things in your life so focus on your main aim not like these things.

HOPE IT HELPS

ALL THE BEST
