U didn't say where u are staying- N, S, E or W?.
Each sector will have some good schs. Choose the ones nearer so u
save travelling time. Try visit MOE website for the top schools in
your area or ask friends' opinion (esp. those with kids). These
schs consistently produce good results.
First of all look for a sch. with affiliation cos if your kid don't
perform well in PSLE, the sec. sch. will still give priority to
your kid. The advantage is that she will still have the same frens
& same sch. culture in sec. sch.
Personally I prefer mission schs. cos they are also single sex.
Less distraction & your kids don't have much opportunity to
interact & have bf/ gf so early.
U might have a problem in getting your kid into good schs. U may
have to move to improve your chances. I know of pple who did just
that!
