I gave the Estonian exam B1 two weeks ago. First time I did self-study and failed the same exam with 5 points, there I noticed I need more speaking practice. However, listening and reading result was quite good(better than İ expected). The second time after some more practice, it improved.
One more secret about learning a language is to study every day at least 10-20 minutes. It helps to keep your memory fresh, otherwise, you forget the language slowly and slowly.
