&gt; No one has done this.<p>Not for coding specifically, but there have been some studies correlating GPA with career success, and the correlation has been found to be very low. But the reason there are very few studies that look at this is that GPA A) isn&#x27;t epistemologically meaningful B) isn&#x27;t a measure in the mathematical sense.<p>&quot;A grade can be regarded only as an inadequate report of an inaccurate judgment by a biased and variable judge of the extent to which a student has attained an undefined level of mastery of an unknown proportion of an indefinite amount of material.&quot; -Paul Dressel
