As there is no topic on Finnish here yet, I’m interested in both Memrise courses and outside resources.
I started out by taking Suomi Monostyle (Level 1, Level 2) here. I like learning the grammar through sentences, so it suits me well, but unfortunately these courses are abandoned now. There’s a level 3, but there are many mistakes in it. The first two are fine. In addition to that, I picked several vocabulary courses.
Outside Memrise, I practice my reading with daily simple news on the YLE website. (Edit: replaced wrong link.)
There’s also a course made by University of Helsinki: A Taste of Finnish. It has lessons with reading/listening material, grammar explanations and quizzes. I haven’t seen all of it yet.
