What about the other 48 simulations?
During this launch phase the rest of the A+ Core 1 library is also open in the practice hub. That is expected to change when paid access launches. Paid access does not exist yet, and when it does it will be enforced by the service, not just hidden in the page. The pricing page shows the planned prices, and this page will be updated before anything changes.
Good to know
- Progress is not saved. Refreshing the page returns you to the hub and clears the current attempt. Accounts and saved score history are not available yet.
- Simulations are designed for desktop and laptop screens. The practice hub is not optimized for phones.
- The simulations are models for learning. They are not a substitute for working on real equipment.
