<p>Brown is more undergrad focused. You will have pretty much all of your classes taught by professors, who will also be much more available to the students outside of class than those concentrating on their graduate students at other schools. Undergrad TA’s tend to TA because they really enjoy that class, and know the actual material better than gradstudents at other places who may be farther removed from that material, and sometimes are “just doing it to get their money”. Of course not everyone fits those stereotypes, but you should not be afraid of undergrad TAs.</p>
