I discovered a mistake in my application after being accepted to a master's program. What should I do? Will my offer be rescinded?
I doubt that it would be rescinded if you tell them what happened and apologize. But failing to tell them might lead to some future charge of fraud, which could be grounds for expulsion. It might depend on how prominent the minor is in the application materials.
It is possible that the error was already noticed and dismissed since your transcripts show your coursework. So your informing them is just &quot;In an abundance of caution, ...&quot; statement.
No one can guarantee an outcome (other than the university), but errors happen. It might have been a bigger issue had you named Math or CS as a minor since that might have been a part of the decision to accept.
