<p>You can set up a freshman course selection at almost any school (that offers all of the science majors) that will keep all of the sciences open so that you can defer the choice of major until later:</p>
<p>Calculus for math, physical science, and engineering majors.
Physics for physics, chemistry, and engineering majors.
Chemistry for chemistry and chemical engineering majors.
Optional biology (at some schools, you need to take chemistry first).</p>
<p>While biology majors often get to take easier versions of math, physics, and/or chemistry, the harder ones should also be accepted.</p>
<p>You can then decide in your sophomore year which direction you want to go. Note that some decisions can be deferred until later; for example, if you decide to go more toward physics, you may be able to keep the options open for physics, astronomy, and geology. Of course, math and statistics will remain an option as long as you keep taking math courses.</p>
<p>If you like several subjects equally, you may want to consider each major’s job and career prospects. In general, math, statistics, and physics majors tend to do better than chemistry and biology majors. If you like chemistry, consider chemical engineering.</p>

<p>If what you actually want is a four year major that samples several sciences, then you probably want something like [Berkeley’s</a> Physical Science Field Major (Plan B)](<a href=“http://sis.berkeley.edu/catalog/gcc_view_req?p_dept_cd=PHYSSCI]Berkeley’s”>http://sis.berkeley.edu/catalog/gcc_view_req?p_dept_cd=PHYSSCI). However, it is being discontinued due to apparent lack of interest. So you may have to check for schools which have something similar, or have a “design your own” major.</p>
