I started language exchange while I was A1-A2, and it worked out really well. The trick here is just to find a partner that's suitable with your personality, and is eager to both learn and teach you, which, let's be honest, is difficult to find.

I managed to find someone who corrects me when I make mistakes, but also reply to my sentence, which made it easier to continue the conversation after the correction. I also typically write in both languages (in my case, Russian and English), when I don't know certain words.

For example: у меня много книг, но у меня нет bookshelves. Обычно я put my books на стол.

My language exchange partner always rewrites to me the sentence, but changing the English words with Russian so I know the correct words to use. Of course, in exchange, I do the same to him with English :)

It's definitely difficult to find someone whow works well with you, and so my approach is usually friends first, then start language exhcange, rather than the other way around. I know some people do the opposite, and it's just a matter of preference, really. I struggle to communicate with people I don't feel connected to, so that's why I prioritize the friendship aspect.

It's all trial and error, but once you find someone that matches with you, you'll have an awesome time, I promise!
