As admission qualification, I beg to differ on the multiple tiers of qualifications. In actual fact, there is only 2 tiers - it's only recognised or not recognised by the organisations. Different agencies have different lists of recognised uni degrees. Better results like 2.1 and above can expect to have a head-start at 1 grade higher.

Once you are admitted, it's solely based on performance. However, scholars are given more high-profile projects that enable them to promote faster. If you are not a scholar and wish to be in fast track, you must build good working relationships with your boss and volunteer for his "hot-potato" issues. Make sure you complete them successfully without your boss "losing" face.
