I require that the student learn the school
very well, practice for competitions 3 hours daily for 5 days every
week and play physical games 3-7 hours a week (not indoor video games)
and study with me when needed. I do NOT want the student to solve
numericals for 12 or 18 hours every day.
You can select 3 or 4 students getting similar ranks in
same school or college as
candidate. If after preparing with me, my student gets significantly
better ranks in prestigious competitions, than those 3 or 4 students
taking coaching elsewhere, I can take the fees. If my student gets
worse ranks than those students or even similar ranks as those, you can
take back the fees. I will not ask for any money in this case.
