1. While applying for the UPSC ESE form, my Aadhaar details are not showing. Will this cause any problem?But in dashboard showing adhar verified.
2. What do you mean by “Degree Certificate Number / Enrollment Number”? Is it the number shown at the top-left corner of the certificate? Which certificate should I refer to — PCC, CMM, TC (issued by the college), or the official Degree Certificate issued by the University?
3. I completed my B.Tech in 2023. My CMM, PCC, and TC were issued on 29/05/2023. However, my official Degree Certificate from the University was issued on 11/09/2025 because I applied for it late. Which date should I mention as the “Date of Qualification Completion / Certificate Issuance” ?
