thanks for replying. No I have just been informed that the MOE reduced the Thai course length from 9 months to 8 months.
Last year when I went in for my final 90 day extension I was informed they would only give me a 60 day one (by the VISA assistant at school) . When I asked did this mean that I will need to apply for 30 day extension this year to complete the course I was told yes.
