How is McGill in these days?

<p>The main question is:
People say that the McGill university is "no longer prestigious university any more", while some argue that it is recovering, and it still has its prestige. As I'm an international student, I'm not really sure about the general information about the McGill university.</p>

<p>Furthermore, in QS university ranking, computer science McGill was 23th place in 2011, but now it is placed 51~100th in 2013. Are there any reasons for this significant change? I'm aiming to do the joint major of business and computer science. </p>
