請問有什麼公開試對升中有用?

Not very high.  What grade is your kid in now?  Is the English standard of your school high?

For Secondary schools - Yes, they will consider but do not expect them putting a lot of weight on it.

KET is good, but I think it would be better to try for PET also, if you are targeting for good (not only just english) Sec. school.

The next test date will be Nov.  Think about it.
