What is God’s grading scale?

This was a question asked recently by one of my teachers. What an intriguing question if you stop to think about it, especially if you’re a teacher like myself. Does God grade on the curve? Does He use a traditional grading scale? If so, what would it take to get an A or B? Maybe He grades using Pass/Fail.

How you choose to answer may depend on a variety of things but you can be sure of this:

God is infinitely loving and God is infinitely holy. He desires that all would come to know Him but He cannot tolerate sin in His presence.

How would you expect a teacher like that to grade?
