To be fair #3 and #4 are abilities I believe can only be learnt through actual work experience. Not much colleges can do in that regard. Sure, group projects, presentations, hosting/participating in workshops etc. did help a bit, but they were all fairly rudimentary in terms of developing those skills. Internships are key.
Couldn't agree more regarding taking English/History courses. I find that understanding and dissecting good English literature isn't any less challenging than any computer science problem.
