Grice in many ways I have to disagree with you. The key word in that sentence is or. What about an individual that got lower than 2 A levels at grade c but then went onto University and got a 2:2 or above, they can apply. Likewise, someone who got 4 straight A's but got under a 2:2 at a top university. Those academic requirements are the bare minimum, they represent that you can apply yourself to study. In many regards, such qualifications are a tick in the right box. Academics alone will not get you onto these schemes, natural aptitude, your personality, your life experiences/choices and your sheer determination will play much more of an important role when it comes to getting selected or not.
