Will St. Peter forgive you for being stupid?

According to common belief, we will ascend to the pearly gates and confront St. Peter, the keeper of the “Keys to the Kingdom” where we will be vetted before we are granted access to heaven.

Most people imagine, I think, that as long as they were not excessively bad in the eyes of God, they will be let in.

But what if they are wrong. What if the ultimate reverse criterion is stupidity?

Would that motivate you to go back to school? Or at least try to make better choices? Are you sure that that good intentions will get you a pass?
