Hello priyanshu!!
Yes, you can write the exam but there is a specific process to do it .  you can re attempt same exams but you have to face all subjects again if you have passed it all and your intense is just score more higer then past one. No need to clarify any thing just go and re submit your new exam form again in any high school. Then you can use any of that marksheet which you want no need to submit old one.
Like deposit your marksheet to board and then you get permission to write. All this process will be handled by the college management
All the best
