I heard quite gd reviews on sakamoto from friends. I would like to try out sakamoto for my primary. 2 son on maths problem sums. Any parents out there interested to start a class for Saturdays or Sundays afternoon class 2.15 to 3.45pm. Let me know. I can ask them to start a class if there are 4 students minimum. It must be the same pri.2 level. It will be at tpy branch, hdb hub. Email me at [email protected] if interested.
