Recommendations: Classes to take for Freshies?

<p>Anybody have any recs for straightforward, not too difficult classes to take for an incoming freshman for environmental science and sustainability major? I'm trying to make my transition as smooth and as 'low stress' as possible for freshman year and i want to be careful with my gpa too. Thanks.</p>
