Hi, Teachers my apology from beginning for such a long post with 26 questions at one go but I need your help to resolve this.

There are 26 questions with 100 marks and after giving the test in computer my score was 90.

I am guessing the 1st one is not correct.But apart from that rest all 25 answers seems correct to me as per different response from different teachers from this forum or from internet. 

I am not sure that even if the 1st one is wrong, then also it will carry 10 marks to bring it down from 100 to 90. There must be another 1 or 2 answers which are not correct and I am not able to find it out. 

Please and please help me in finding those hidden ones.

Philip thanks so much for your help.
Agree with Philip 100%. Some of the questions were definitely written in such a way that raises doubts about the author's depth in the language. It's unfortunate that you have to work with such confusion.
Students: Are you brave enough to let our tutors analyse your pronunciation?
Thanks Dim so much for your words. But this is how we have to deal with. Unfortunately we have to score 80% or more to be successful in the exam and few answers are really confusing. Emotion: sad
I believe you got the ski question wrong and I have issues with these two, because for # 17, the normal collocation is " I quit smoking two years ago....", or I stoppd smoking tqo years ago. "To smoke..." is wrong.
# 18, I don;t know what this one is asking. Other than that, you did quite well.
  • 17.My supervisor advised me quit worrying, as
    the deadline had been pushed back.
    (A) advised
    (B) quit
    (C) as
    (D) had been
  • 18.I really look forward for studying Japanese to prepare
    for my trip to Tokyo.
    (A) look forward
    (B) for studying
    (C) to prepare
    (D) for my trip
Hi Dim, thanks for your quick reply.

Yes you are correct. the 1st ski one is wrong. It should be "Neither Do I".

For #17 and #18, please pardon me as I failed to follow you for for these 2, that you mentioned above.

I have attached one snapshot from my above post which ask about "Find the Mistake in the Sentence".

Do you mean for # 5, 6 and 8, my responses are correct?

Please advise.

Thanks Again for your help.
Students: We have free audio pronunciation exercises.
Without sounding harsh, I can only say these are not good sentences and should not be used as a test!

Natural collocation:
Advised me not to worry...
Look forward to my trip / studying in Japan
I quit smoking ....
thanks Dim a lot.
