If you like SJC, then its good to swap to SJPS. But please prepare to have more tight schedule and more time for revision. Kids need sometime to adapt to the new exam scope....and in most cases......Will encounter some vast drop in the very first beginning.
You need to view the overall 4 subjects 5 or above rate, and each subject 5+ rate...You will notice SPC is improving......year by year....
like this year Maths , maths 1 /2, physics...
really quite good.
