Cullen’s Abc’s DIY Online Preschool is designed to be used up to three days a week, with each day consisting of up to 2 to 3 hours of curriculum. Miss Cullen recommends that you schedule at least two days a week. To determine how many days you are going to do, consider how much time you can dedicate each day to the class and the developmental stage of your child. If you would like to get feedback from Miss Cullen send her an email.
