i think you should just go ahead and apply. get a good reference letter etc. these days the applications are way down and I think you've still got a good chance.
Interesting. You're positive the NA isn't actually necessary? I'm curious about these examples. I didn't look closely at it, but PT 71.S1.Q11 seems to be about pollution. Is that the right reference? PT means PrepTest, right?
Wait is this expiration in reference to purchasing PTs through Cambridge? I've never had a problem with buying/downloading from Cambridge, but guessing I should buy the few PTs I haven't bought already?
