Took the real deal

Tested today and honestly feel like I messed up BIG time. I have a habit of flagging qs so I have approximately flagged 20 qs per block which is ALOT. As soon as I started, first block went a bit mid bcs I was a bit anxiety but then I settled in and my subsequent blocks were okay I guess? Felt a bit confident but then took the last block and I have guessed almost 60% of the questions in my last block. I genuinely feel like I might just fail but that is my worst fear bcs I’ve spent way too much time, energy effort into it. Failing would literally be the end of me. I don’t necessarily think the paper was crazy hard like it felt doable but 2 of my blocks were hard. Is the 80 experimental question thing true??? Please share your experiences. I feel like I might just die waiting for the result. Nbme scores were 72-77 and New free120 was 73%.
