I learned English as a 2nd language as well and I am therefore able to understand where you might struggle. My University dissertation was based around what makes learning a 2nd language easier and what can boost the ability to learn. I have also got an IELTS certificate and have lived in the UK for a bit over 5 years now. I have also studied 3 years of German in the Goethe Institut and have further experience with what it means to learn languages completely different to your native language. My native language is Greek and I am also confident in my ability to teach Greek as a native or 2nd language.
What might sometimes look like a hard and lengthy process when learning a languages can be helped by using some tools that life gives us everyday.
