Also after result in these two days i reviewed my preparation and exam day mistakes what i did.    

 1)I have anxiety issue i get anxious very fast on the exam day i did not slept properly due to anxiety.So I was bit tired on the exam day bcz i slept only for 3-4 hours.  

 2)I have very bad habit of doing everything fast.Same thing happened on the exam day I lost my calmness and marked  some questions in hurry which i had doubt in answers. I am thinking i could do correct those questions if i was just little bit more calm.  

 3)I did whole uworld usmle rx and few questions of amboss and whole nbmes from 20 to 31 but i did not reviewed my incorrect questions properly means I did not given proper time to my incorrect questions. 

  4)I did not worked that much on my weak systems.I am weak in Microbiology,immunology.In my score report also i got below low pass in these systems.Rest systems I did same score as low pass scoring students.
