My brother wants to switch to Electrical Engineering and possibly do a Master's degree (with thesis). He also has a BSc and MSc degree in physics but not much formal training in EE (except some basic electronics, solid-state physics and advanced electromagnetism courses).
Since the most important factor in grad school applications is research, he has tried to contact professors and labs so many times for even non-paid internships, with no results. The other option is to apply to BSc degree or just about any MSc degrees in order to take the prerequisite courses.
How should he proceed? What are some advantages or disadvantages of getting a BSc in EE (using some credits from the previous degree) vs doing a Master's program in EE with thesis that accept him and take the prerequisites courses?
