In the meantime, you can submit the form. If you kid is accepted by any one of the DSS, then you are asked to either (1) give up the government allotment or (2) give up the place in the DSS. It's no harm. But I understand what you feel, as what I was last year. My case was even worse then yours - as there is no good primary school within my district except Yaumatei Catholic with very keen competition. We have no additional credit in any school that would benefit from the 1st lucky draw.
