i have my #1 rec in the bag (i think) with a physics professor, whose class i was the only student in that semester (luckily i got an A). as an engineering physics major, i didn't get the opportunity to take many liberal arts classes. the liberal arts class that i did take, that had a major writing component to it, i got an A in. so, i think that teacher would be a good candidate for a recommendation, but the class was an entry level philosophy course taught by a GTA. also, i'm 1.5 to 2 years removed from his class, and he likely won't remember me specifically. i called the philosophy department, and the GTA is going to be around this fall. he's a very laid back guy and i think i would be able to get a good recommendation from him. i'm thinking of contacting him by email within a couple of weeks. is getting my #2 rec from a GTA very acceptable?
