So I'm in the delimma of not knowing any of my professors in huge classes. I accept that, so I think I will just try and specific profs to write me a rec after meeting with them and such. But what's the best way to approach this? Is it more effective to write them an email introducing myself, and asking if we can meet so they can get to know me better, or should I try to find them when they're at their office so it's more personable when I ask them in person? Any advice is appreciated!
