I'm so sorry to hear about that. I took it recently in Philly as well. I'm a US-IMG and I remember I was usually always the last person out of the room except for like 1-2 encounters. I know I made many mistakes and the thought of failing CS terrifies me. The thing is, I didn't feel horrible or even great when I left, I had mixed feelings. The day just went by so quick I barely had time to think. How did you prep? Do you think you made a lot of mistakes? I know it's getting tough for us IMGs, they recently raised the passing criteria and will fail about 8% more IMGs. The test is clearly not about knowing English well and having basic communication skills.
I'm slightly nervous because most of the people taking the exam with me were all AMGs. Everyone seemed to be having a great time, laughing, smiling, and finishing encounters super early. I was trying to stay calm but the difference between AMGs and IMGs was noticeable.
