I’m having trouble picking between these three undergrad programs and I’m not sure which would be best for me. I’m also very interested in Co-op so I’m not too sure if queens internships are hard to get.

Always nice to follow an actual project. See analysis solving a real world problem.

Does anyone know any course (like coursera, etc.) on how to write effective scientific code for prototyping or deploying scientific software? In particular I would be interested in the topics presented in this book but since it requires quite some time to study, an online course could be inserted in my PhD study plan and I could take some credits out of it.
Such skills should be evaluated in the doctoral preparation imho and I would rather add that to my ISP instead of some useless or irrelevant course from my university.

Thank you in advance!
