If you are working, I suggest you to go British Council to sttend the Businees course.
I can tell you Englishtown is not good actually. When trying to attend their lesson, they did not allow me to try their lesson, just forced me to sign the contract,I asked them several times on that day that if I could give them money month by month or not,they said I should sign the contact and even I was not interested in this course , I also needed to give money to them. I phoned to the government and CEF, they said that they couldn't do anything as it was their policy. I did not believed them , but they phone to me many times, it's so annoying, so I paid the money finally.I joined it last year. It's about $18800.
After joining Englishtown, I thought their lessons were not systematic and I couldn't learn anything. If you pass F.5 Syllubus B/ IELTS=5, you may not learn what you need in this course. They only provide oral lesson in small class with all student at same leve in the center and online lesson, but actually the students usually were not at the same level in speaking. Also, in workshops, usually there are a lot of student from lower level, they usually ask a lot of simple question and speak Cantonese.It is difficult to learn anything. Furthermore, you will face a lot of technical problems but they usually said that there're no problems.Also, if you want to 考空姐. It needs a good presentation skill in English, Cantonese and Putonghua. I suggest you to have a individual tutorial class. As I believe that one-to-one class will be suitable for your level, also you can ask whatever you want, the topic is not fixed like Englishtown/ WSI, so you can learn a lot of thing in a short period of time.
If you wanna see the Englishtown lesson structure, I can give you my account to try it. As I think it's not that useful, after receiving CEF, I haven't attended any lesson.
Should you have any problem, pls feel free to find me by yahoo hk email.
參考: I have been studying in Englishtown for 1 year, British Council business eng course for one year.
