Hello,

Could you please mention about which exam score you're asking for validity?  If you could specify the question clearly, we can answer you accurately.

Mention the name of exam here in comment section to know the validity of the respective exam's score card.

However, Your profile says you're an engineering aspirant in graduation,  so I assume you're asking about  GATE score validity, then the answer is The score shall be valid for 3 years from the date the GATE results are announced.

If not about GATE, then mention down  in the comment section the name of exam.
