Thank you all for the replies,
The main reason i wanted to take the pre course course, was to get more confident with and improve my grammar. Here is a link to the course. http://www.cactustefl.com/tefl/online_c ... se_id=2827
After doing this, the weekender and hopefully some volunteer work, I will feel better equipped looking for work back in Thailand or any where else in S.E Asia.
As i mentioned before my ultimate goal would be to get a CELTA. I've contacted a course provider in Bangkok, and was told i would need a pre university qualification to get on the course or a very strong application. As i don't have a pre uni qualification i was hoping that doing the shorter courses and getting as much work experience as possible, would one day help me get on a CELTA course.
