I should've mentioned that I actually took Spanish classes a few years before Duolingo. Those classes taught me the grammar and why the rules exist, but I didn't memorize many words (or I forgot) and I had serious trouble understanding actual Spanish speakers.
Duolingo "teaches" alternate tenses weirdly and IMO too late. But it does well for memorizing words, and it has people speaking with actual Spanish accents and forces you to understand them. So it's particularly helpful for me.
