Hi – I was getting ready to register my son for Henle 3 class and I understand it is $25 a month, but when I was checking out it said my card would be charged once a month, 36 times? I do not understand this? Would a year be 12 times? or Is it that I need to cancel the subscription when he is finished next May/June? Thanks!

You can cancel anytime.  I have set payments up to end at the end of three years.  Most of my students stick around with me for three years, at least.  Those who stick around for a fourth, fifth, or sixth year, get to attend classes for free.  I like to reward long-term students.
