I will not repeat. Myabe u can try 插班 K2. My daughter is 1206 baby and she took the 插班 interview last summer. now studying K2 at SH. If u really like TL/St clare, u can try 插班 to these 2 kinder.
If I were you, I'll stay at the current KG, try to apply st clare's and TL primary 2 yrs later (chance of being accepted by these 2 primary schools are not as low as SPK and SH); wait for the luck of lucky draw (Wanchai is an excellent district for girls!)
