> Hello,
>
> I am planning to attend a tesol course, do you know what is the
> difference between Cambridge CELTA and Trinity TESOL?
No difference in status. Trinity places more stress on phonology.
> Which is the most widely known and recognised?
CELTA. Some people haven't heard of Trinity. You wouldn't want to
work for people who hadn't.
> Is £650-700 a reasonable cost for a summer course?
You won't get much cheaper. Minimum course length should be 1 month,
which would be extremely hard work to cover the syllabus. Don't do a
course that takes any less time.
> Do qualified English non-native speakers find job in UK?
Not with grammar like that. Yes, they do, but only with a lot of
experience compared to recently qualified native speakers.
> Many thanks!
Don't mention it.
