I have been teaching foreign languages (English, German) at various educational institutions for more than 12 years now. I have been teaching IELTS/TOEFL since 5 years now.The methods I use to teach are unique and tailored to an individual’ s needs. All students are different and it is very important to find their strengths, focus on them and use them correctly to develop their learning abilities.I use a lot of different techniques, and every aspect of learning the language is involved; Reading, Speaking, Listening and Writing.I put my students at ease straight away by creating the ideal learning environment to progress quickly and easily.

I just want to say thanks to Radix Tree and my teacher Jen. I wanted to get a real good score in my CELBAN Exam but was not able to achieve it. By taking online classes with Radix Tree I have not only enjoyed but the course also reinforced many of my concepts.  I was a little reluctant in the beginning that how the online course would help me but believe me it has been really easy and convenient. I could take classes from my home and time of the classes were also arranged according to my convenience. Teacher got to know actually where I was lacking behind in my 1 hr free assessment class and she suggested me to opt 15 Days Intensive Preparatory Course of CELBAN and after 15 days of rigorous classes this time when I appeared in my CELBAN exam  I got 10 in Listening, 10 in Reading, 8 in Speaking and 8 in Writing … whipppieee !!

Thank you so much for trying to make a difference!
