There is severe competition for many of our courses and you should not therefore be surprised if your application is initially placed on a waiting list. This is done so that we may give fair and equal consideration to all the applications which are received by UCAS by the first closing date of 15 January. Since we do not receive the final 'on-time' application forms until late January, we put many earlier applications on the waiting list. It means that we wish to look at your application again in the light of the later UCAS forms which we receive. We will write to you if we put your application on this list and will invite you to send us any further and additional information on your application if you wish, for example, results of mock examinations, revised A level predictions, or further statements in support of your application.
I don't think it's too much to worry about
