2. Duolingo. Maybe at the same time. It's a gamified system of learning words. Glorified flashcards. But you do learn some words. That's good. Problem is, you don't learn those words in context.
What you get is determined by who volunteered to build the module. The Russian module is decent. I can have elementary conversations with Russians. I have a hell of a time with high frequency sounds, age and mileage, so I have to focus really hard to follow along with the modules.
The Spanish duolingo is more like a flash card than the Russian module. It's OK.
