Attached please find a pdf file with the cumulatives in rank order
I used the following procedure to compute the cumulative:
Projects 40pts (out of 100)
Exams 35pts (out of 100)
Homeworks 20pts (out of 100)
participation 5pts (out of 100)
The three project parts and the demo were all taken together to be 10pts each
homeworks were each taken to be 5pts
Exams were both taken to be 17.5pts each
participation grade is a numeric translation of the letter grade (in a 1-5 range).
If you see any discrepancies or have reservations about the way I computed the cumulative, let me know ASAP.
