Exactly the same experience. Some questions were so ambiguous. Fingers crossed.The first 3 blocks were like I was fighting Satan himself. Question were incredibly hard and vague. Barely finished each block with seconds to spare. The rest of the blocks felt easier but I still finished second before the timer expired. Used all my break time. Last person to leave the center.
Felt like Satan had won. I had done NBME 7 and thought that was hard but the exam was so much worse.
Ohhh...Gee...Do you think Uworld and Mtb is good enough...Or were most concepts not from there?..I gave a brief account of what it was like. Questions were for the most part IM. Stems were looooong. And not 5-6 questions per block. 35-40 questions would be like short essays.
