I'm already starting my third week of graduate school and I have so much free time that I don't know what to do... I would consider myself a very proactive person- I start and finish most of my work as soon as it's assigned, I network with professors to find a research topic/advisor and acquired a 10 hr/week TA position within the first week of classes. I just don't find any of the work I've been assigned challenging... Maybe its because I don't have a topic yet and its only week 3, but I expected graduate school to be much more demanding. I just hope the program I decided to attend isn't "mediocre". Is the initial grad school experience supposed to start easy, then get painfully difficult??
