As per the latest update available on May 24, 2022, the Punjab School Education Board (PSEB) has not yet announced the exact date for the declaration of the 12th STD result. However, the board has mentioned that the result is likely to be declared by the end of May or in the first week of June.
Please note that this information might be outdated, and the PSEB may have released the results since then. To obtain the most up-to-date information, I recommend visiting the official website of the Punjab School Education Board or contacting them directly.
