The resources that help me in my personal practice

Okay, so I did mention in my previous post that the hardest aspect of language for me is grammar...

But grammar is super important for understanding the structure of the language.

http://www.ets.org/toefl if the service that in my opinion doesn't need a lot of description - everyone, who studies English at more or less professional level has either considered passing the TOEFL exam or has already done that. 

Then also this year I'm studying the methodology of teaching English, and this resource from 

Cambridge https://www.cambridgeenglish.org/teachingqualifications/ is something I've been considering for a little while. I've heard a lot of it and I like the fact that it gives the international diploma. Also it's pretty cool to have a document from Cambridge.

And another really good service https://www.pearson.com/english/myenglishlab.html has a lot of helpful resources and samples and I sometimes use them in my practice.

Right at this moment I'm not actively studying anything, instead of that I'm just focusing on working and getting knowledge from my jobs, but I am planning on getting a TKT certificate in the future.
