No. In fact it is much worse!
Many LACs and smaller colleges offer a 3-2 program. Few students actually complete them. Why? Columbia, for example, requires an overall and eng-specific GPA of 3.3 with no grade ever below a 3.0 in any eng-specific class. To me, that’s harder than getting in as a frosh. At a 4-year engineering school if you have a bad semester and then get on the ball all is forgiven by the time you are interviewing for jobs as a senior; have a bad semester at Arcadia and you won’t be an engineer. Is that better?
Also after 3 years in college many kids just want to be done with the damn thing. At 3:2 schools they see their friends graduating in a year and by filling out a change of major slip they can too. Or they can pack up for parts-unknown, a school where they don’t know anyone, and slog it out for 2 more tough years in engineering. There aren’t a lot of takers.
3-2 programs are like lures that colleges without an engineering school dangle in front of prospective students, who think they are “keeping their options open”. If you are seriously considering this route, ask Arcadia how many students they sent off to each of the partners in each of the past 3 or so years. My guess is almost none. And ucbalumnus pointed out in an earlier thread that http://apps.carleton.edu/curricular/physics/for_students/department_links/engineering/questions/ indicates that about 50 to 60 students are interested (i.e. 16 to 20 students per year), but only 0 to 3 actually transfer to Columbia or WUStL to finish the 3+2 program.
Lastly if you think having 2 degrees is somehow “better” in the eyes of future employers, its not. If you get thru an acredited engineering program everyone knows you have enough math chops to handle anything you need to learn.
