I can honestly say wish I had you as my professor for this class, or at least stumbled across your videos sooner

im sure its not my prof's fault, but my brain struggles to be sharp and quick like the others so when she just speeds through a lecture I'm always lost on concepts that aren't even all that difficult. thank goodness for this video!
