Step 2 CK question, please help!

Several programs require Step 2 CK to rank you. That being said, some use it as a formality while others actually look at this. This question is better suited for the advisors at your medical school. Sorry this response isn't too much of a help!

Thanks for the reply. I was told by one of my programs that they need Step 2 CK in order to rank me as a formality and that it won't at all affect my ranking. I suppose I am left with no choice then, am I? I hope it won't hurt me.

Yup really no choice. Nothing you can really do.

A 35-year-old woman is brought to the emergency department because of worsening pain and swelling of her right knee
for the past 2 days. She has been taking acetaminophen for the knee pain during the past 2 days, but the pain is worse
today. She has not had any trauma to the knee or any previous problems with her joints. She is otherwise healthy and
she currently takes an oral contraceptive. She is sexually active and has a 10-year-old son who lives with her. She is a
receptionist at a local hotel and she tells you she must stand often while working. She is 160 cm (5 ft 3 in) tall and weighs
52 kg (115 lb); BMI is 20 kg/m2
. Temperature is 37.9°C (98.9°F). The right knee is erythematous, swollen, and tender;
there is pain on movement. No other joints are affected. X-ray of the knee shows an effusion but no structural
