It is an interesting question. Years ago, I developed an algorithm to predict chemisty final grades bases on the first three weeks work, as based on prior students. I put the predictions away until after the year, then went back and compared. The corelations were significant, 92 percent of the students were within +-2 points of the prediction.

Actually, your question sounds much like a test question. We don't do those, but will critique your thinking on it.
