If something goes wrong

I cannot see the Practice page.
Practice opens once your internship is active. Check My Day for your start date.
A wire will not connect.
Drop the end of the wire right on the terminal dot, not beside it.
The panel looks tiny on my phone.
Turn the phone sideways, or use a larger screen for wiring.
Check says something is missing but I cannot find it.
Read the first line of the message. It names the part or wire. Fix that one and check again.

Leaving it

  • There is nothing to remove. Close the tab when you are done.
