Econ vs. Quant Econ math usage

<p>How freely is the calc and linear algebra from the required math classes used in the core Econ 100/105 series for the above majors. I have completed all the math and received A's but it was over a year ago. I just want to have a better sense of how much Math review I should do before transferring next fall. Are there certain math concepts that seem to pop up quite a bit?</p>

<p>p.s. How intense was the Stats UD series for the Quant Econ major? I also applied to berkeley and all they required was a lower div calc based stats class why does UCI have to go so overkill on the stats with a whole year's worth?</p>
