Thank you for reply, but i don't want to reappear from this same board because as per me they are corrupt and there is no transperent system. Also i want to improve marks and clear chemistry. So i don't want to take risk in same board again with tough evaluation and checking criteria. I just asked if it is possible to do so, there will any issue ahead if i will just use one marksheet ?

NILABH Hii, it's alright if you're not satisfied with your current board and results. So you can get in touch with your current school staff committee and discuss with a bold reason that you wish to change your school and board. They shall guide you through a smooth procedure. Also, remember that the process could be a hectic one as it's about changing the board, pattern and examination forms.

So, without taking much load, start working hard and consult thoroughly before you take a decision. Also, to conclude, it's completely ok to go for a fresh start and improve your areas of interest.

Wish you all success and the best !!
