Hi aspirant, Don't worry at the counselling then you have to show your original transcript. Now if you give a soft copy that is not the issue. Final admission they will take the original paper. So try to collect before admission pocedure if you won't submit the original document you will lose you seat . Try to collect the document.  

Hello Zubeen,

You can try uploading the 12th marksheet softcopy but at the time of admission counselling the requirement is of the original mrksheet so according to me you have to collect you marksheet from your school at the earliest
