Hkust appeal letter

Hello, I am an Indonesian student applying for the HKUST undergraduate program in Engineering for the 2017/2018 term.
So, I have just finished my National exam and got the results a few days ago. My conditional offer was to achieve an overall score of 85%, mathematics score of 85%, and physics sore of 85%. My overall score is 88.9%, with the score of math 95%, and physics 82.5%. Based on my score, I do not pass as my physics score lacks 2.5% from the minimum requirements. Thus I have written an appeal letter and mailed it to them yesterday, on 5th May 2017.
My questions are

  1. How are my chances of getting an acceptance, based on my score and my conditional offer?
  2. How long will I get a reply email, stating whether my appeal got accepted or not?
  3. Are there any examples of an applicant to successfully appeal on the previous years?

Thank you
