Hello Aspirant,

With 2 different boards you cannot do this practice

But if you practice it from same board then you can proceed for answer written below.

See there is no any legal provision of Dummy concept in schools but students who join some coaching institutions for their preparation of entrance examinations, they only use to visit schools either to give examination or for practical, not for attending regular classes and schools also allow them but board has not allowed this practice yet.

If you practice this dummy concept and then in class 12th if you change your mind to give your regular attendance in school then you can definitely do this because legally you are the regular student of that particular school.

I hope this information helps you.

Good Luck!!
