hello there,

As per your query , you filled your 10th board form with first signature and after that you had changed your signature with a New signature. So, in Math MCQ test Attendance, there is no need to be worried as their is no issue in signature but if you are making this mistake in govt related documents then surely you will have to bear some problems. So, in other you must use your first signature which was signed in your 10th board form.

See, it is an appropriate way to use only one signature in whole 10th board Examination.

Hope you got my point and if you still have issue then you can make a new query related to this .

Thank you :)
