Interval Identification

[Waigin]

I found that when I do the interval identification descending (around lesson 16), sometime, he will tell me that it's a Major 3rd (or any major) and when I press Major 3rd, it will tell me that I was wrong and it was a Minor 3rd. When I listen before to choose, it was the good one. I decided to try with the show answer touch. I saw a few time, that he tell me it's a Major and when I touch the show answer, it will tell me that it's a minor and I was right. :strange:
