Here is the context:
Suppose you want to study CS (and work as a dev after graduation)
at CMU which is a top 3 CS program, however SCS acceptance rate is say 7%.
You can also go through the ECE track AND take enough CS courses as there is
as decent amount of overlap in the majors and take additional CS courses as electives
or as a minor.
ECE is in School of engineering … school of engineering acceptance rate is almost 4x that of SCS. So essentially you can “backdoor” into an equivalent of a CS degree from CMU.
As a employer (in quant finance) a ECE major with a CS minor from CMU looks as good a SCS major …
