daily word - grades?

Do you see salvation as a binary state, with the sheep on one side and the goats on the other? You could liken this to academic classes that are based on the pass/fail system. But most academic work is based on a scale of grades, so there are several levels of performance. What grade would you expect to get on a test of basic Christian doctrine? Do you think that such a test will be required for the entrance into the Kingdom of God? What grade would you expect to get on being kind to the least of these? What grade would you get on not causing offenses or causing little ones to stumble? How do you think all these things will factor in?
