Can I use actual IMC time for the requirements in 61.109(a)(3)? I needed extra instrument time for my VFR checkride but it was cloudy for my lesson. My CFII and I turned it into an introduction to IFR lesson and we flew 0.3 actual and 0.3 simulated (with the hood) and did 1 ILS approach in IMC.

61.109(a)(3) says that the following instrument training is required:


  3 hours of flight training in a single-engine airplane on the control and maneuvering of an airplane solely by reference to
  instruments, including straight and level flight, constant airspeed
  climbs and descents, turns to a heading, recovery from unusual flight
  attitudes, radio communications, and the use of navigation
  systems/facilities and radar services appropriate to instrument
  flight;


Is it correct to assume that I can use the IMC time for this?
Sure can.  FAR 61.109 makes no distinction between flight in hard IMC and simulated in an aircraft using a view limiting device.
