<p>Stats is a great course, but hardness really depends on your HS teacher and background. If you have already aced AP Bio, then Enviro can be really easy since it is just a subset of bio. OTOH, your ES teacher may pile on a lot of busy work – and field trips for beach clean-up.</p>
<p>Sure, any biz school would rather see Stats over Enviro. But, senior course selection depends on what else you have and what else is offered. Colleges would prefer to see Calc instead of Stats, for example. Colleges would also prefer to see four years each of the standard academic disciplines.</p>
