Last year in my A Levels I had offers for A*AA at Durham and AAA at York - in my results I got AAB with one A close to an A* and the B close to an A, but Durham wouldn't let me in because I wasn't counted as a near miss. I did get a place at York, but my heart was set on Durham so I got remarks. These went up by a lot and I got a solid A*AA so phoned Durham, but they had given my place away!
I was given deferred entry for next year and put on a waiting list for this year, so decided to take a gap year and declined York. A few days later Durham then phoned me up to say I'd moved up the waiting list!!
I was so happy, so even if you miss your offers there is still hope!
