I'm sure that being the first person to graduate in your family would be seen as an accomplishment. When you grow up without that expectation, yet manage to graduate anyway, you have overcome the odds. If you can write the PS in such a way as to demonstrate that this was a huge personal triumph, then that is how they will see it.
It's a plus, particularly if you can show a pattern of SES disadvantage. Don't expect it to be a URM-level boost, but it counts.
Sure they care but I wouldn't build my app around that fact (in case you're thinking about doing this).
Sure they care but I wouldn't build my app around that fact (in case you're thinking about doing this). First gen college grads aren't really that rare or special. If you've done great things than being the first to go to college makes your accomplishments that much more special but it doesn't itself give you much boost IMO.
i wonder what it would have been like in a family of college/grad school graduates. i wouldn't change my family for a second...just wonder!
