Need immediate assistance. Tests tomorrow!

Hello,

I am going to take my Air law, and general technical knoweldge written exams tomorrow, and I found myself stuck with something a day before my test.

1) How do you figure your TORA, TODA, and ASDA.
I was under the assumption that .

TORA = RUNWAY length + stopway

TODA = Runway length + clearway

ASDA = runwaylength + stopway

where do i add a displaced threshold if there is one? Any of the above?

Thanks,
CG
