I’ll advice against it unless you love math and have an extremely solid work/study ethic. Especially if you go to UCSD, it is a *brutal* program. If I went back to school now full time I’m not sure I would be able to complete it, even with 10+ years experience under my belt.
Something to consider is to get one of the lighter weight degrees, or major is something you like (art, music, history) and get the compsci minor. Its better to finish with something than to not finish at all. Take advantage of the extra free time and work on some side projects.
