Not sure if this is the correct place to post this, but I received the NSF award yesterday and have a question for others that were awarded this year or in the past. Is it best to accept the stipend during the first three years? Considering the stipend at my school raises a bit each year, it would seem to be best financially to use the NSF stipend the first three years. Are there any reasons to defer the three years of financial support if you are currently enrolled in a graduate program? Thanks for any help!
