USMLE Step 1 Experience by Ayaz Mehmood (Score : 99/266)

USMLE Step 1 Experience by Ayaz Mehmood (Score : 99/266)
Salam everyone, let me start in the name of Allah who’s the greatest benefactor of all mankind. I am going to write a detailed composition regarding preparation for USMLE Step 1. I am a final year student at King Edward Medical University and I took my exam on June 10th. Final year is the year before internship/ house job in Pakistan. I just got my scores: 99/266



Let me introduce some myths surrounding USMLE Step 1 which are especially prevalent within Pakistan; I am not too sure about India because I heard their students typically appear in their final years.


 Myth number 1:Do not appear for USMLE Step 1 within your graduation

 Verdict: Baseless, illogical reasoning

Explanation: This is so prevalent in Pakistan it’s almost pathetic. One of the biggest concerns surrounding our students is that Step 1 is a huge risk to be taken before graduation. Let me put it in another way: Step1 would always remain a risk whenever it is taken, …

Australian Medical Council AMC Part 1 Guide - Experience and Tips

AMC Part 1 by Dr. Asad Khizar Malik (Rank : 77/620) Australian Medical Council  Guide - Experience and Tips
Salam people, let me start in the name of Allah who’s the greatest benefactor of all mankind. Hope everyone is doing great. I'll try to write as much as I can for the people who are due to various reasons more interested in joining Australian Hospitals for post-grad training as compared to the USMLE pathway.

I am a graduate of King Edward Medical University, class of 2004-2010. I did my 6 months house job after graduation in Mayo Hospital, and after that, i gave my AMC Part 1 in November, 2010 from Brisbane. With the grace of Allah, I passed that in first attempt.

So lets start with the discussion here, but PLEASE NOTE THAT IT IS ENTIRELY MY PERSONAL EXPERIENCE AND REASONING WHY I PREFERRED AUSTRALIA OVER USA FOR RESIDENCY.

First thing in mind that comes with post grad training in Pakistani doctors minds is: Which way to go after graduation? That is a very tough decision that is …

The tree that never had to fight For sun and sky and air and light, But stood out in the open rain And always got its share and rain, Never became a forest king, But lived and died a scrubby thing… Good timber does not grow with ease, The stronger wind, the stronger trees.
Getting yourself educated in the desi manner i.e. through the Board of Intermediate and Secondary Education is one of the top most challenges of today’s society. Matriculation seems difficult at that time, but when you enter FSc, you realize that matric was the easiest job in the world.  Those obese books of intermediate part I and part II are the worst enemies one can ever have.  People say Medical is tougher, but I find one basic difference in both. When you enter a medical college, y…

USMLE Step 2 CK experience by Rizwan Khan (254)

IN THE NAME OF ALLAH THE MOST BENEFICENT AND MERCIFUL

     I recently got done with Step 2 CK exam & I want to elaborate my experience and the mistakes that I made during my prep so that any of my colleagues who are preparing for this exam might benefit from them. I wont go much in detail about how to prepare and where to prepare from since it is already highly debated on the forum and in the previous posts but would focus more on my personal experience and the bad choices which I made during the preparation phase.
