Comment Math degree with emphasis on CS theory (Score 1) 433
A math degree would require less laboratory classes and less projects. You could do the studying to learn u/g level mathematical concepts at your own time and you would mostly have to worry about homeworks, midterms and exams and not so much about big (team) projects.
Projects in CS curriculums are extremely time-consuming. And most importantly, after all these years of s/w engineering experience, you don't need them. You have already acquired most of or more than the skills that these classes are designed to teach.
On the other hand, what you most likely lack is formal CS theory training. Being able to grasp deep algorithmic and complexity concepts, discrete math, numerical analysis, linear algebra, data structures etc would undoubtedly help you become a better engineer.
So my suggestion is a Math degree with as many CS theory courses as possible. Keep in mind that some of them will have projects, e.g., numerical analysis or algorithms, but those projects will actually teach _you_ something and are usually not as time consuming as big S/W engineering design and analysis or compilers projects.
