is waiting list on ESF kinder can apply next year again

We got put on waiting list on applying 2015 K1, may I know can we apply 2016 K1 again next year (as we are small months baby), or apply to k2 next year or can only apply ESF Primary later? As their website stated the year level for each year kids. Pls advice thank you!
And anyone know why ESF even don't give all 230 applicants a fair interview? Is there any hidden factor for getting an interview?
