With W3Schools Plus group buy, you pay per slot for a shared account that is already activated, making the per-person cost far cheaper than a solo subscription. You get full access to the monthly W3Schools Plus, including ad-free learning, exercises, and certificates issued to whoever logs in with the shared credential.
Because this is a credential-based shared access, there are important rules to follow. Do not change the password, do not change the account email, and do not log out other members' devices from W3Schools. These rules exist so every group member can keep learning without interruptions. If you break them, the admin may disable your slot without a refund since it disrupts other users.
Right now the private 1-user plan is open, while the group plan that splits one account among up to 3 people is still being prepared and will launch soon. When the group plan is available, simply pick the plan, pay via QRIS, and wait for the admin to activate the account and send the credentials. If the group is not full yet, you can still reserve your slot and the admin will start the cycle once the minimum number of members is reached.
