How easy was it for you to get into IOM MBBS in Nepal?

There is a lot of discussion about how hard is to make it to IOM MBBS program in Nepal? There are tales such as someone tried 4th time and made it to IOM or some made it first time top ten etc. For an average student; is IOM just a dream despite dreaming to become an MBBS doctor someday?
Could someone with experience answer how easy/difficult was it for you to get into IOM?
