If the gym was open and you miss a class (Doctor appointment, illness, etc), you are welcome to come to open gym for free and that counts as the make up lesson. You must sign in at open gym with the date and time you missed. Make ups must be done within four weeks of missing class. Make up lessons at open gym are not an option when the gym is closed for a holiday. These dates average out over the school year to ensure your child gets an average of 4 lessons a month, as explained on the release form.
