This is good advice. The reason BU's LEAP program initially gained popularity in the mid 2000's is because it was pretty much the only option for non-engineers to get into an engineering Masters program. The kicker was that nearly every person received substantial scholarship, I believe I had around 75% scholarship when I started. So the cost of attending was on par or even cheaper than attending a public university. Also, at that time BU's grad BME rank was like #7 or something in US News and World Report so it was prestigious, almost fully funded, and located in a cool city. I haven't kept up with LEAP recently but even by the end of my time there things drastically changed (e.g. firing of Helaine was a massive hit) and they made a huge cutback in funding. I basically stopped recommending it to people.
Bottom line is that there are most likely many ways of achieving your end goal and everyone should really explore all options available. If attending LEAP is the best fit, I would recommend at least completing every possible pre-requisite course you can at a local community college to save money and then just do the last of the courses through LEAP. But if you can find other programs that are open to accepting non-engineering undergrads, look into those too. Some engineering disciplines are more flexible about this. BME is often pretty flexible with what undergrad majors they accept. But say electrical engineering might not be as flexible.
