Dear poorni,
Please go through this thread
Kumon/Beestar/Gideon/Aloha etc...... Classes for kids regarding Kumon classes. Personally I have a friend who was a tutor in Kumon before and she says that the method is good but you must see the centre with good tutors.
For music, my son learns it in school . Drawing you check with your CCs. They will have it once a week classes-like pencil drawings, cartoon drawings, paintings etc. They also will holiday course for 7 days/10 days everyday. Since schools are closing today, this evening, I am going to my CC to enroll him in pencil drawing course.
