The Scots, who won the old Five Nations title in 1999, have already claimed the scalps of France and England at Murrayfield this year.
And, despite their defeat in Wales last month, Frank Hadden's team find themselves level on four points with three other countries.
But a win in Dublin over fellow title-chasers Ireland next Saturday will leave Scotland with just a trip to Italy in their final game to handle.
However, the Edinburgh Gunners centre maintains that a low-key approach to the final two matches will prove the best policy.
Di Rollo said: "We are not getting too far ahead of ourselves.
"We have two away games coming up against Ireland and Italy, and England are the only team to have won away in the Six Nations this year - in Rome.
"So playing away from home is always going to be tough, especially at Lansdowne Road.
"But we have put ourselves in a position where, if we play well, we can take chances.
"And, if we defend well, there are not many teams who will score points against us.
"We have given ourselves a chance and, hopefully, we will take a lot of confidence from the wins over France and England.
"Now we have to take that into the final two matches starting in Dublin next week."
But Di Rollo, 28, concedes that the game at Lansdowne Road offers no guarantees with the Scots chasing their first win over the Irish since September 2001.
He said: "I didn't see the Ireland win over Wales - I was out for lunch and a bit of 'recovering' as well after the England game the day before.
"I saw part of it but I will watch it more this week.
"But the Irish team is full of good players - Geordan Murphy, Brian O'Driscoll, Ronan O'Gara, Gordon D'Arcy and Shane Horgan - the list is endless.
"They are all good players and it would be foolish to single out any one of them.
"But, if we can hold our shape, hopefully, we can achieve a result next weekend.
"Teams are taking points off each other across the board this year, which makes it exciting to watch.
"For the fans, having four teams all on four points will make for a brilliant finale.
"For the impartial supporter, that final weekend could be something really special."
The Edinburgh player has thanked physiotherapist Bob Stewart for his role in ensuring his fitness for the one of the best days in his life.
Di Rollo had been forced to withdraw from the team for the defeat in Wales last month due to a hamstring injury and was rated "touch and go" for the Calcutta Cup clash.
Now Di Rollo is grateful to be fully fit again for the match in Ireland next Saturday - courtesy of the British & Irish Lions and Scotland physio.
He said: "You grow up wanting to play for Scotland against England but to beat them as well was unbelievable.
"I was totally ecstatic and it was great for all the guys who have been involved for the last few years to get the win against France and then England.
"But I had been touch and go for much of the week leading up to the England game.
"However, I worked well with Bob Stewart, who performed miracles for me.
"He gave me the confidence over the injury going into the game.
"My fitness was only confirmed on the Thursday before the game when I came in for extra work."
