Lesson needs rework – Tone - Learn Perfect Pitch! Review

The lesson that teaches perfect 4th and 5th recognition is beyond impossible for me. I had no trouble breezing through the first 7 lessons but day 8 is my limit. They sound utterly, 100% without a doubt, identical to me. They need to redo this lesson and find some way of making them easier to differentiate because after a week of doing this one lesson over and over, I cannot hear a shred of a difference between the two.
