Reddit reviews 201 Swedish Verbs: Fully Conjugated in All the Tenses (201 Verbs Series)

Do not use Rosetta Stone it is such a scam.

If you're willing to pay money, use Babbel. I've used it for Swedish and it is outstanding. They have a very balanced, reasonable rotation of topics so that you're not just stuck learning grammar for twenty lessons or cultural things for twenty lessons, it's all mixed in together.

And there are interesting words and phrases they use where they'll explain the cultural significance of that word or why it's used.

It also has speech recognition to help develop your pronunciation, too. And, the mobile app lets you pick and choose which lessons or topics to download so you can focus on developing vocabulary in certain areas without overloading your phone/tablet's storage.

I also recommend this book - https://www.amazon.com/gp/product/0812005287/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

You'll also want to mix in other authentic materials - news sites are a great source (svt.se is good). I also like reading TheLocal.se - it's in English but you can learn interesting facts about Swedish culture, history, current events and politics there, which is always helpful when studying a foreign language.
