Admit cards are typically issued by the organizing authority of an examination or recruitment process. These cards serve as official permission for candidates to appear for the examination or physical tests. They contain important details such as the candidate's name, roll number, examination venue, date, and timing.
In the case of the Sashastra Seema Bal (SSB) Constable Tradesman PET PST (Physical Efficiency Test and Physical Standard Test), the admit card would likely be issued by the SSB or the relevant recruitment authority. The admit card may be available for download on the official website of the SSB or the organization responsible for the recruitment process.
