To cover the same material an Extra has covered today ("similar
difficulty"), your new test would have to include the material covered in
all three current tests (with over 120 questions in one sitting).

I expect it would be a longer test than todays Extra, but probably not 120
questions (since some things, like band segments for example, would be the
same as for the learner-permit level), and perhaps not necessarily in one
sitting -- could be structured to be taken in 2 (or 3?) sessions for those
who are intimidated by lengthy exams or have weak bladders.

My Extra exam was 100 questions. You were allowed 3.5 hours to complete it.
