Dear Khushboo, 

Unfortunately, it is a NO. 10th Marksheet is not a valid id proof for neet. Please carry original copy of either PAN Card, Voters Id, Aadhar Card. Without an Identity card, you will not be allowed to the examination hall. It is important to carry identity proof because the invigilators need to know and have a proof that the person who has filled in the application form and the one who is attending the exam are one and the same.
