Andy Robinson is convinced England have emerged from a troubled RBS 6 Nations campaign stronger for the experience and ready to take on the best sides in the world.

The England head coach reflected on the lessons learned from a frustrating campaign, in which his side lost their first three games by the grand total of just nine points.

A single score against Wales, France and Ireland could have meant Saturday's victory over Scotland at Twickenham was to seal the Grand Slam instead of the Calcutta Cup and fourth place in the championship.

The seven-try victory, inspired by Jamie Noon's hat-trick, was a record win over the beleaguered Scots and England finished the championship on a high with many a lesson learned.

''Our next two games in an England shirt are Australia and New Zealand in November and if we were playing them in a month's time I'd be hugely looking forward to that,'' said Robinson.

''We have gone to the wire in four games (including the defeat to Australia in November) and lost those four games.

''That is bitterly disappointing to us all. We've had to learn how to win those games and I think that is something this team now understands.

''Ultimately we will look back on this and think 'if only'. We have lost by one score in three matches and that is the most frustrating part about this.

''International sport is won by small margins and we have to make sure that when we play and it comes to the wire, our belief and attention to detail means we we have the ability to win those games.''

England had lacked experience and the killer touch in the early rounds as Robinson, bedevilled by injuries to key men, set about building a new-look side.

With Jonny Wilkinson, Mike Tindall, Will Greenwood, Richard Hill, Julian White, Phil Vickery and Jason Robinson watching from the sidelines for some or all of the championship, Robinson's hand was forced.

He had to find a new prop. The midfield hole needed to be plugged. Where were the leaders? The questions took some time to be answered, but Robinson is now certain England are ahead of schedule.

''We've moved forward as a team,'' said Robinson.

''This Six Nations has helped the long-term planning because our leadership has been tested. We have had to find leaders. We have had to play players in back-to-back games and they have learned from their mistakes in a tough environment.

''I think we have made as much progress as I could have wanted. We have found some players who have come through very strongly. Someone like Jamie Noon needed a bit of time to grow and we have seen that. How he has developed has been one of the major pluses of the campaign."

Robinson and the coaches have all admitted making mistakes along the way. The selection of Newcastle's Mathew Tait in the centre for the Wales game was clearly one of those. Tait was dropped immediately and has not figured since.

Kicking coach Dave Alred conceded he was to blame for the fiasco against France that saw Charlie Hodgson and Olly Barkley switch the responsibilities between them only to miss six penalties and a drop goal.

But Robinson insists mistakes have to be made in the development stages of a side. After all, it took Sir Clive Woodward three botched attempts before England sealed the Grand Slam in 2003.

''I am passionate about England and I have confidence in the players we have selected and the process we have gone through to select those players,'' said Robinson. ''I have made mistakes and I will always put my hands up.''
