<p>I have heard that many people prefer professors, but is it really better?</p>
<p>Taking into consideration that in the BEST univeristies, which I won't mention because you all know, most of the courses are taught by TAs.</p>
<p>Some TAs might actually teach better than some professors. Generally speaking, though, professors are better than TAs because professors are more experienced. So with professors, you can expect a more consistent quality.</p>
<p>most courses are not taught by TAs at the 'BEST' universities...</p>
<p>TA/ Teaching Fellows are graduate students and are in schools ranging from Harvard, Yale, Penn, Columbia, Cornell (other 3 are more undergrad focused and will have limited TA) to state/ local universities.</p>
<p>Fewer than 5% of courses are taught by TAs at top universities...and those are almost always entry level classes in English, Math and foreign languages. TAs generally have a more active role in leading discussion sessions, but in those sessions, they do not teach, the simply lead discussions.</p>
<p>At Penn, in the larger classes, the prof gives the lectures and the TA teaches the recitation sessions. Some TAs do teach better than professors.</p>
