<p>If you want to be an electrical engineer, get your BS in EE - that is the only way to get the full breadth of the field, taking your BS in any other area will limit you to a couple of specific specialties of EE. The same applies to the other fields - if you change your mind are more interested in ChemE, then major in that instead. If you cannot make up your mind, then pick one and take some extra coursework in the other field - if you reach the end of your bachelors and decide you made the wrong decision, those extra courses will help you switch for your masters.</p>
<p>As far as a masters degree, you won't really know what you should take until you are nearly done with your bachelors - there are just too many variables for me to make a suggestion. As before, if you want to be an EE, an MSEE would generally be the best choice, but you may also (or instead) want a masters in math, or physics, or may want to switch fields entirely.</p>
<p>As far as management degrees, you want at least a few years of experience before going after one of these degrees - a management degree without experience is a hindrance, not an asset. At my company, you realistically need about 7-8 years of experience (including time spent getting advanced degrees) before you can be considered for management, although there are a few routes around that. Still, get at least to the level of "competent engineer" before you start looking for management. Also, realize that these degrees are only required for actual management positions - I work alongside some of the highest-level engineers in my massive company, and none of them have management degrees, but a heck of a lot of them have PhD's and ALL of them have masters.</p>
