1. The first 2 weeks is pretty much self study time on IREX theory, get up to date on it because you have an exam the first week. The 2nd week you will be introduced to MCC training material, you will study this for your sim sessions and there is also a exam at the end of the 2nd week.
2. As far as I know, everyone has graduated and successfully completed the training. I do not think QLink would go through all this with much expense to want to let you go. Then again, if you dont put the hard work in your digging your own grave.
Like Mr Cat said, put your head down and work damn bloody hard. Reap the benefits of this great opportunity.
