Rocket Spanish

Just wondering have learners found that Rocket Spanish prepares them for speaking Iberian Spanish.  I am thinking of beginning to learn Spanish but would be learning it to speak it in Spain and not in South America..  Thanks

Vosotros is included but the focus is Latin American Spanish.

I had the same issue when learning Spanish in recent years.  A Spaniard I knew replied “What does it matter?  They'll know your a foreigner either way.”  Much research produced the same results.  I'm English, and there is a world of difference between the accents and to a lesser extent, slang, between the south-east and Newcastle (aka “Geordie”) or Liverpool ("Scouse').  Nevertheless, English is English.
