Yes, swapping your 10th certificate and degree in the PSSSB online form can be an issue. During document verification, officials match uploaded documents with the details you entered. If your qualification details (like 10th and degree) are mismatched, they may raise objections. It could lead to rejection if they consider it misinformation or carelessness. You should inform PSSSB immediately through email or helpline if the correction is allowed. Carry all original documents and be ready to explain honestly at verification.
