Undecided and very nervous

<p>I'm leaning towards a biology major but I'm really not sure what I want to study. If I go in undecided and take the core classes and some electives, how hard will it be to satisfy bio requirements later on if that's what I choose? Please help!</p>

<p>you might end up taking chem and calculus freshman year, which is what I'll likely do so I have options later on</p>

<p>chem and calculus satisfy the science core requirement ( in addition to frontier of science)......so i would take those two earlier rather than later</p>

<p>is it important to take the most challenging chem course and work really hard or take an easier one and get a good grade?</p>

<p>basically its up to you.......but since im planning on going to med school, i would go with the easier class/good grade to get a high GPA</p>
