no need to worry. many private kindergarten doesn't have enough student. many has moved to other country or don't let kid attend PN due to Convid.
My son (born in august) got rejected by greenfield the first round in October. We tried again in the third round in next april and got accepted. greenfield long beach used to have 4 to 6 nos. PN classes. This year has only two.
also my son cried the whole time during cannan interview and got accepted.
