Ans: For “Type A: Families / Small Groups / Individuals” account, each account could register a maximum of 3 participants aged below 18 and a maximum of 5 participants aged 18 or above.

For “Type B: Schools / Groups / Charities” account, only the details of ONE contact person need to be registered. There is no need to register students' or participants' information online. If schools/organisations would like to register for activities, it only needs to enter the number of students/participants at the page of online registration.

Ans: Parents may update their personal information (including details of both adults and children) ONLY IF no activities have previously been registered under their account, either online or on-site. In other words, once a participant has been successfully registered for any physical activity, online seminar, online workshop, or InnoTech DIY@Home learning kit, whether online or on-site, the participant's details can no longer be changed. (If any changes are necessary, parents must first cancel all successfully registered activities for the participant before amending the participant's personal information in “My Account”. However, activities for which the registration deadline has already passed cannot be canceled.)
