Checkride Checklist Question

A fellow student and I were dsicussing something,
and we certainly intent to ask our instructors.

There are some points in the flight where the simple
(but important) checklist needs to occur.
For example, after takeoff clean-up, after landing clean-up,
before landing check list, etc . . .
Places where the basic steps are pretty easy to remember.

So - DURING THE CHECKRIDE - how important is it to pull out the
actual checklist as opposed to just doing the checklist.
I'm not talking about the complicated stuff, or things
with a lot of items.

Does the Examiner want to see the actual checklist?
Or is "getting it right" enough?
You know, something with 4 steps could take 3 seconds to complete.
Pulling out the checklist makes it 10 seconds.

Would people mind commenting on whether we have to
"go through the motions" to be "right", or to "pass".
I mean, how many people actually pull out the checklist
for the before-landing checklist in a 152?
Feul, Seatbelts, carb-heat, landing lights, etc . . .

Thanks!
