Well, if you are on waiting list in the year 2009-2010 and would have one unit allocated to you even in the reserve team, I suggest you not apply the year 2010-2011 as you would be forzen on the coming year. That means you are waste of time time and hope. Its is better to apply for the next time (i.e. 2011-2012)
Well, It is only my suggestion only. You may consider whether it is fit to you.
