Stat 20/21 vs. upper div

<p>I'm an intended Econ/MCB double major (with AP Stats) and I need to take at least a semester of statistics. Does anyone know how Stat 20/21 compares to upper div. classes such as 131A or 134 in terms of difficulty, content, and practicality? Any general advice or course recommendations would be greatly appreciated :)</p>

<p>Everyone should know Stats 134. That’s just my opinion.</p>
