Review your PTS. Technically they can not ask you to do or ask you questions outside the PTS.

Also, instrument approaches are about speed and control. If you rush it, you will get behind the airplane. Work the flight at your tempo and not ATC's or the examiner's.

Check out this article that I posted, ILS Approaches and Airspeed Control, which talks about shooting approaches into a high density, complex airport like LAX in a CRJ200. If the heavy metal pilots can do it, you can too. You may realize that it is the same no matter which airport you go into or what airplane you are flying.

Once YOU control the flight, you control the outcome.

Good luck and let us know how you do...!
