I have times before felt eternal time quite intensively studied foreign languages. And now I thought I'd forgotten enough and maybe I should deal with Russian and Japanese again.
First I wanted to buy a few language courses, but somehow I found the then but not so great. The main reason was that the courses are all for beginners, but I have just a few basic knowledge of Russian (which will also come back gradually). Fortunately, there is the World Wide Web and I must say, I've discovered so some treasures. And best of all, that most of it is even free.
Today is a page for Russian: learnrussian.rt.com
This page is ( unfortunately ) in English. So you should already understand. But otherwise I find it so far great. There are a hundred lessons, each with grammatics and some vocabulary. For complete beginners, the site is probably not suitable, because I think the individual topics are handled fairly quickly. But for re-entrants it is exactly the right thing.
In each lesson, the grammar is not only explained, but also tasks have to be solved. These are partly listening comprehension tasks (with nice dialogues, which are also not old-fashioned), questions that have to be answered or one must use suitable words.
If you do not have Russian characters on your keyboard, you do not have to worry about it. The page has extra one that can be called. However, I find it more comfortable to write on my normal keyboard.
When you register on the site, it saves your personal progress.
At the end of five lessons, you can take a test on the topics conveyed. There is also an evaluation for this. This is also saved.
I really like the site. At the moment, I'm only at lesson 12, because I do not have a lesson every day. But it really helps to recruit knowledge that is stored in my brain somewhere again.
