Studying English language by yourself is quite possible, but such learning process requires from a student a lot of strength, energy and time as well as such traits of character as being diligent, hard-working and single-minded.

What does it mean to know a foreign language? Today it is possible to find out your level of English even without leaving home due to many online English test level. It is necessary to take into account that such tests do not reflect your language level precisely because usually they are found at Internet resources connected with foreign language schools. These schools offer paid or offline resources to assess your language level precisely. So, it means that even receiving results based on CEFR system you should remember about possible online tests inaccuracies. Moreover, some tests based on their content are absolutely unable to assess your language knowledge at advanced levels (C1-C2) objectively.

The first thing you need to remember is that foreign language level can only be checked in practice. To define your real language skills by yourself is almost impossible even with the help of Internet-tests as they only define grammar knowledge and very restricted vocabulary. That is why it is better not to trust these results very much as they may differ in real life situations.

Identifying any foreign language level including English all experts pay attention to the four key skills: listening, reading, speaking and writing. It is these skills that are checked at various international exams. It is obvious that an English test level can help to assess only the two first criteria, though in real life it is more important to be able to express yourself in speaking and writing.
