So, what grade did you receive for this commendable effort? Westminster, being Dutch Calvinist in its theology, I very much doubt that you would have received an 'A' since they certainly would not want you to think too highly of yourself.
A grade of anything less than an 'F' would not be consistent with 'Total Depravity' and if it was better than that, obviously God was totally respopnible and you should have been dismissed from the school for copying God's work. :-)
Palmer Robertson is a gracious man, paper and course grade were an A.
