<p>Here is an example of what a frosh year schedule for chemical engineering looks like (may vary slightly by school; a student with AP credit might start in a more advanced course in some subjects):</p>
<p>Semester 1:
Calculus 1
General chemistry 1
H/SS breadth
H/SS breadth or engineering intro course</p>
<p>Semester 2:
Calculus 2
General chemistry 2
Physics 1
H/SS breadth or engineering intro course</p>
<p>Note that a student following this frosh year plan will be able to switch to physics, chemistry, or math without delaying graduation. Depending on the H/SS courses chosen, switching to an H/SS major can also be done without delaying graduation. But a student who does not start with something reasonably similar (or more advanced courses based on AP credit) is more likely to delay graduation if switching into chemical engineering, although a student who does follow such a plan as a non-engineering frosh should be able switch to chemical engineering without delaying graduation, assuming no administrative barriers or impaction constraints.</p>
<p>The administrative barriers or impaction constraints on changing major at some schools are a different consideration entirely. These need to be researched for each school before applying (since schools with administrative barriers or impaction may require applying to the major).</p>
