<p>sports61KH, im not sure like what college you may be in or will be attending, but definately i have asked many friends from UC's, they have divded into like 3 to 4 classes, which makes it hard to skip out cause like it might be like cell resp and evolution, which you may not need evolution but definately you cant not learn respiration.</p>
<p>yeah so i've heard that it may be better (at UCs) to take all classes in the sequence, since u would probably need something and it may be a prereq for a higher class</p>
