UCD and UCB, Tag Agreement/Transfer

<p>I'm currently in my second semester, summing up 32 units, and I TAG'd Econ AB. Math/Econ are prevalent subjects for the major, it is required of me to take Linear Alg, Calc I, II and III, Statistics, Differential Eqs, and the primary Economics classes. I have a preference towards Math, so I don't mind them at all. It's just the TAG agreement and my interest in Berkeley's Econ programs I'm worried about. I'm hopeful of acquiring 40 units by the end of the Summer semester, after which I'll be submitting my TAG to UCD. My GPA's ~3.7, but I have not shown leadership skills in my position in any way. But I have recently applied for a volunteer job for a corporation that would enhance my skills in my current field of interest, in which I have a very good chance of getting in. My question is.. what else should I do to increase my chances of getting into UCB? And are there any other requirements when it comes to the TAG that are not stated on Assist? That is, what else would I need to do to secure an acceptance letter?</p>
