Love the idea of AI grading the answers, hopefully this can be extended to marking/evaluating/grading subjective manuscripts. For me there's none is more boring than marking/evaluating/grading manuscripts. I prefer hard labor like gardening or farming than doing that activities although I'm quite good at evaluating stuffs I think. Can you please elaborate how you do this and based on what metrics/scheme/etc the answers are being evaluated?
