some of the guest replies are from me. Not all. If you read meticulously, you can make out. Also it makes a lot of difference between 0.5 2a and full 2a coach becuase i/you would never opt for waiting in class 2a as its less likely to clear. Also this info is only available at our website. I would not regard much difference between s14 or s15,but greater difference between ab1 and a1
