Since there is no history on PN class. I only can let u know how I feel about the school in K1-K3. Their academic level is abit high compare to the neighbour kindergartens. Will be similar level as other Kowloon Tong kindergarten. SJC is tranditional and low-profile kindergarten.
If u search thro the comments of this school in previous years, probably u will know why they need to organize PN class. (pls don't ask what the comments were, 自己做功課啦。)
