First off, I wasn’t sure which category to put this in, so sorry if this wasn’t the best one.
My goal is to go to grad school for a masters in biomedical engineering. Now, I know that my ideal track would be to undergrad major in mechanical engineering and move on from there, as that would be the best educational and employable path as far as I know, but I’ve heard that it is VERY hard to get into engineering – especially mechanical – at any school with a good engineering program.
Would it make a difference to admissions officers if I declared my major as chemical engineering compared to mechanical?
Personally I’m more interested in chemical than mechanical, but I think mech is more suited to biomed. Will I still be well off if I go chemical eng. undergrad to biomed eng. grad?
Thanks
It honestly won’t make that much of a difference, many schools are more flexible with their majors than you think. Most applications also have an 'Undecided Engineering Major" if that makes you feel better. A lot of people in your situation pick this as they have an end game, but just can’t pick the right engineering major. Your freshman adviser will be able to help you with it.
I’m a computer science major, but from what I know, as long as you take some core classes, you would probably be fine if you have a major in chemical engineering, especially if that is what you are interested in. Don’t settle on mechanical if you don’t like it; wait till you get to the college and talk with people in your field until you commit.
Good luck! 
It depends on the school. For instance the UCs admit by major. Check each school to find out.
