How difficult is the oral part?. Time is limited so obviously they
cannot ask every thing.

No, but displaying weakness on a subject matter will usually draw more
questions, or requests for clarification, on that subject. In my
experience, the examiner will arrive with a plan for each section of the
exam, so that the important stuff will be covered.

For stuff that isn't often used, ex:// FAR minute details, you can ask
to look it up. BS'ing is usually a bad plan if you really don't know
something.

The actual time period is at the discretion of the examiner. There is
no egg timer running during the test.

Also, the oral portion doesn't end when you get into the airplane for
the practical portion. The oral can theoretically continue right up to
when your temporary certificate is issued.
