Looking for advice on how to structure my learning.

Hello, I started learning russian about a year ago, I put it down for awhile because I felt like i wasn't really learning the language as much as I was learning how to do the test things on duolingo.
I'm looking at starting again but i wanted some advice from people who have learnt a second language.

What should I be doing, is there something I should focus on in particular?

Sorry for the late reply. Have your tried Penguin? It's very good.
