Sorry about resurrecting this but I am also confused by this. I was given the impression at the time, some 30 years ago, that when I was in full time education I would still be receiving national insurance contributions. However, I have also found a gap for the 3 years I was at university. Is there any way to fill up these 3 years? Until recently I was not even aware of this issue. (It is obviously well past usual 6 years)
