<p>Suppose you take 15 units per quarter or semester. 15 quarter units = 10 semester units, since each quarter unit = 2/3 semester unit.</p>
<p>If you transfer to a CC on the quarter system or stay at UCSD, you will not be behind on units, since you will take 15 units for two quarters in winter and spring, resulting in a total of 45 quarter units = 30 semester units for the academic year.</p>
<p>If you transfer to a CC on the semester system, you will have 15 quarter units for the fall and 15 semester units for the spring. This equals 37.5 quarter units = 25 semester units for the academic year. This means that your frosh year will be 7.5 quarter units = 5 semester units short of a full year of course work.</p>
<p>If you came in with lots of AP or college credit from high school, that may not be too much of a concern. But if not, you would have to take course overloads or summer sessions to “catch up” on units.</p>
<p>Another issue if you transfer to a CC on the semester system is that if you are taking sequenced courses (e.g. typical lower division math courses like calculus), the breaks between quarter system courses and semester system courses will not line up, so you may end up having to repeat some of what you already took. For example, if you took a quarter system calculus 1 course at UCSD, that covers only 2/3 of a semester system calculus 1 course, so if you transfer to a semester system CC, you would not be able to go into its calculus 2 course.</p>
<p>If you do transfer to a CC, you may want to check for nearby quarter system CCs where the courses you want to take match one-to-one with UCSD courses according to [Welcome</a> to ASSIST](<a href=“http://www.assist.org%5DWelcome”>http://www.assist.org) , particularly if you are taking sequenced courses.</p>
<p>If a semester system CC is most convenient (for location purposes), but you are in sequenced courses that misalign between quarter and semester systems, you may want to consider finishing the academic year at either UCSD or a nearby quarter system CC (even if it is less convenient), then switching to a more convenient semester system CC the next year.</p>
