<p>Do you really need to have taken econ 101a in order to do well in 101b? is it "really" a prereq?</p>
<p>bump anyone? also can u declare econ while taking 101b 1st?</p>
<p>yes u can take 101b first to declare</p>
<p>but how come 101a is a prereq for 101b and 100a not a prereq for 100b? will i have a hard time taking 101b first?</p>
<p>sorry. I take that back. You have to finish 101a first.</p>
<p>I'm not sure why it's a prereq for 101b. You'll have to talk to one of the advisers</p>
