Summer Session and Summer Language Institute

<p>I have heard that J-term is mentally exhausting (in fact, I read that somewhere on this forum)... how is the 3 1/2 week (ish) summer session in comparison?</p>

<p>Additionally, I realize the language institution is supposed to be intensive but I would like any feedback from anyone who has done it/has friends that have done it, and what they though of the program.</p>

<p>Thank you!</p>
