Does anyone know where I can find any content to help study for the exam

I haven't used my switch for some time and wanted to play it. I tried for it to connect to the tv but it keep telling me the Nintedo Switch isnt connected. The light comes on from the dock to show that it is connceted but doesn't project the screen of the switch onto the tv. I've tried disconnecting all wires and reconnecting it, even in a specific order but still nothing. I have no idea why this happens, could it be the dock itself is faulty or could it be from the switch? ports? cords? I'm really lost on how to resolve this.
