If I buy a 3 months or 6 months program, do I have to finish it in that period of time?
No. The 3 months and 6 months programs will help you know how long you will finish the whole program if you just attend one hour a week. There is no time limit on how fast or how slow you want to finish the hours given to you on the program.
What happens if I buy an hour lesson and want to continue the long term program? Can I transfer that one hour and deduct it from the long term program?
