Taking Econ 134 concurrently with 101B

<p>It says the prerequisite for 134 is 100B/101B. I will be taking 101B next sem, can I take 134 while taking 101B without struggling too much? Also, can I phase 2 Econ 134? I really need math 54, so I am thinking about Math 54 and Econ 101B for phase 1.
Thanks!</p>

<p>anybody??
