Help - Going to College

[dvander at pluto.njcc.com]

I am going to college next year and I am wondering what the main
differences are between these majors: chemistry, biochemistry,
molecular biology, microbiology, genetics.  Is it easy to double major
in any of them?  I was also wondering what would be the best major for
preparation for neurology or could they all be valid.  I think some
colleges actually offer a major in it but neither of the colleges that
Im thinking of offer it.   Do you have an opinion as the which of
these colleges is better?:  U Minnesota, Twin Cities or U Colorado,
Boulder.  

Please respond to any of these questions as soon as possible
Thanks
-Dave
