The defender was part of the Scottish side given a footballing lesson by Spain in midweek as Craig Levein's side narrowly missed out of the play-offs.
Berra knows it will be a different kind of challenge at the Hawthorns with local pride at stake but is aware points are vital to both sides after poor starts to the campaign.
He said: "This will be a completely different game from the Spain one. Scotland were always going to be underdogs against Spain.
"As a defender, it certainly gives you a different view of the game to line up against the world and European champions.
"It's a totally different challenge to the British game with the front five or six guys very small and skilful. I think I only had to head the ball once in normal play!
"Now I've got the derby and the Premier League is already completely different to international football and this will be a real skelter game."
Berra believes Wolves need to cut out silly errors as they look to end a run of four successive defeats.
He said: "We may have lost four on the bounce but everyone is still positive and it's nothing a victory wouldn't put right.
"There'd be no better place to do it than at West Brom. We need to get back to winning ways.
"There have been mistakes and we've been punished for them so we need to cut those errors out.
"We need to give ourselves a chance by not conceding goals as we have done recently.
"You can't afford to go 1-0 or 2-0 down in this league and expect to keep coming back.
"We've also not had the rub of the green and, if we can cut out those mistakes, maybe we'll get a bit of luck as well."
Berra knows how important the derby is to both sets of fans and will relish trying to give Wolves followers the local bragging rights.
He said: "The atmosphere was great at both of the derbies last season.
"Away from home it's particularly electric in derby games with the abuse from the home fans but that's what players relish.
"You just want to go out and do your job and make sure you keep your focus throughout.
"Coming from Edinburgh I knew all about the Hearts-Hibernian rivalry before playing in those games as I'd been brought up into it.
"But this game is just as big for people from around here and we know that there's a lot at stake and how much it means to the fans.
"A win would certainly change things around for us very quickly."
