I did INFO1010 last year, and I will say it wasn't as easy as I thought it was going to be. You are tested on Microsoft Word, Excel and Access. I found the Word part easy but the other two not as much. But each person's different.
And no the second computer lab is not compulsory, I did not go to a single one. Though you should still register in one just in case.
Edit: I'm at Ourimbah too, in case that's somehow relevant.
