We don't have the capacity to pause and save your lab.

Maximum lab time for a session is 9.5 hours with extensions.

Although the timer keeps counting down, you may exit your lab and then come back and resume provided you return before the timer ends your lab.

Please plan your time to complete one module in your session. You may come back and take any lab as many times as you like. Always start at the beginning of a lab module. Previous work is not required.
