PRACTICAL GUIDE

PRACTICAL
Written: Scheme for proteins Practical: Unknown solution: lactose
Viva: what is lactose, type of bond, type of bond in cellulose and glycogen 

PRACTICAL........scheme of carbohydrates+lactose(unknown solution)   MINOR VIVA....what is lactose,galactose,name other disaccharides,what is maltose,diff. between maltose and isomaltose,source of maltose,source ofsucrose.................. + don't get confuse but use your common sense while choosing unknown solution as lipids look greasy,carbohydrates appear mostly as clear fluid and proteins are turbid white or show white bubbles or suspension on top. also they haven't added (atleast in our group) any other protein than albumin or globulin i.e there are no proteoses or peptones ,casein or arginine.)      HOPE THAT IT WILL HELP A LITTLE :)  ]]]]]                               

write scheme of detection of albumin. normal urine . viva:how u detected urea? is urea present in normal urine? its quantity? quantity of normal urine? polyurea? 

practical:milk.....n viva:milk protein name...??...which tests detect it..???milk sugar...??show the test that u hv performed to detect it...n what is the procedure of this test..

15mins... Scheme for detecting proteins
Detect organic + non-organic constituents of normal urine...
Viva: what are organic components of normal urine... What's Uric acid?

What Happens During Practical?

As soon as you enter, you will be asked to handover your practical notebook and take a card. There are many cards, you take one and go to your seat. There is a practical written on your card, which may be one of these:
--Examination of Urine (either normal or abnormal)
--Biochemistry of Milk
--Unknown Solution

In the first 15 minutes, you write your practical on the sheet provided to you. If it's scheme, you draw the scheme. If it's milk or urine, you make the table.

Next, they give you new sheets and take away old ones. Now you are asked to perform, There are nearly 1:30 hrs for performing. After you perform, you just write the results and the conclusion on the sheet and hand it over.

After that you wait a LOOOOOOONG time for Sir Shakeel to come and take your viva. Your viva will be related to your practical mostly; however, sir Shakeel can ask anything else as well so BEWARE.

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 …

FSc Premedical Guide - How to fly high.. Unsa Athar Your 40% needs to be excellent to get into KEMU or  some other good place.

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.
