I took English lessons from Sandra for 2 months.  I learned many useful self-study methods which involved different media: news, radio, comicbooks, magazines, novels, etc.. with her assistance.
She recorded the pronunciation of certain words which were my weakness and gave me the recorded tape to practise with.  I used it frequently and practised again and again.  She lent me a novel with a tape as well.
During the lesson, she examined my questions and assignments:  compositions, radio news dictation, vocabulary, idioms, etc..
As well, she closely observed my pronunciation and grammar and carefully corrected me in the middle of conversation.
It was a short time for me.  However, I learned many things.  I expect that these lessons may become a strong foundation for my future in English. 
Thank-you Sandra!
