transferring to college of engineering

I was admitted to notre dame as a mathematics major in College of science(second year) and I am interested in double majoring in computer science. I recently learned that it would be impossible to double major computer science in the college of science unless I do the five years program. I would like to ask if it is possible to transfer to College of Engineering as a computer science major and double major in mathematics?

Long Story short, No. What you want to do is only offered as a five year program across colleges, and isn’t available in a four year span. Regardless of what college you start from, it’s still the same five year program.
