glasgowdavid said:thank you everyone who has replied , i am overwhelmed, seriously that strangers can take so much time and effort, it is so encouraging and i know why now that when i head down i will be able to call on some of you for a leg up as the social isolation is the motivation for considering a group and the resultant social occasions that will result from that camaraderie in the group.
reading between the lines it would seem that since i am there for 8 weeks initially that it may be beneficial to join one of the recommended groups and after a short period i consider the private tutor separately or in tandem.
now how do i get the PM element working?!
For a private teacher, Sofia Bohmer is amazing and would cost you much less than US500 a month! Check out her page: http://sofiabohmer.wordpress.com/
I was choosing between group class or private but decided that I wanted to go at my pace, as opposed to wait for everyone else or have other people wait for me. Her class is not only about grammar but about colloquialism and she has an ability to explain all the tricky rules in a clear methodical way. Being a socioliguistics student, I guess that's her craft. She's more a friend to me than my profesora.
Good luck and have fun!
