<p>Can someone help me clarify the meaning of this: </p>
<p>In each subgroup, one of the two courses must be 5 
units and carry either laboratory/demonstration or 
Writing II credit. For students entering Fall Quarter 
2009 through Fall Quarter 2011, the laboratory requirement is reduced to one 5-unit course from either 
subgroup. Other courses in the subgroups may be 4 
units.</p>
