Hi aspirant, in respect of your question, no there is no law which prohibits you front doing so. You can use only one marksheet for getting admission. There is no need to share this with high education university or on government jobs.

If you are taking the 10th exam from the same board two times the later result will be in force. The previous one will be cancelled. But you joined in a different board and passed the exam. Generally, you can appear in the same class examination for division improvement.

Thank you.
