AP Chemistry and AP Environmental Science on May 12th - Same time? How can I resolve?

<p>i have a lot of friends who were in this same situation last year.</p>

<p>the consensus was that the late chem exam was SIGNIFICANTLY easier than the regular one.</p>

<p>(though of course this was probably due to what the teacher emphasized throughout the year, what they had recently review, etc.)… so really i gather that the tests are equivalent. Teachers across the world teach so many different things in different ways, so how could any test be objectively “harder” than another?</p>
