<p>good points, both of you, imo there are benefits to both sides.
taking 18-19 units may guarantee 4 yr graduation, but one can also take 14-15 w/ in addition to summer units. taking 18-19 may prepare you mentally for when you get to junior/senior years (where my orientation prof mentioned most students drop out from).</p>
<p>but one cannot forget that with taking only 14-15 (4 classes) it would be easier to focus in on classes and bring up that G.P.A.</p>
