Hello Aspirant,

Yes, a CBSE 10th study certificate (or original marksheet) is usually needed during engineering, for DOB and academic qualification verification. If you've lost the original, you can always apply for a duplicate marksheet or certificate from CBSE - either through their official website or from the concerned regional office. At the time of counselling, make sure to bring the duplicate and a copy of the FIR or affidavit (if applicable).
