Why UsmleSource

Most people that fail the USMLE step 2 CS do so in data gathering! Why do people fail in data gathering? because most of the courses available, including OSCE, FA and UW, concentrate so much on the individual case rather than the approach.

The folks that design USMLE knowingly mix the features of a few diseases so that your differential is wide open. It is important to realize that the key to success is not your diagnosis but your approach! That is why we have taken all the common symptoms that you see in USMLE CS, and provided with our "symptom based approach" that works no matter what the individual scenario might be!

Since practice is one of the most important parts of preparation for this examination, we developed software to enable you to practice the cases timed including the patient note.                       ...more

User Reviews

I feel very confident going into the exam after reviewing these cases. Being this is my second attempt I found a strong correlation between my prior cases and the cases offered here. The information is being handed to you in the most discrete and clear ways possible. Take advantage of it! Not only are the cases interactive but also the forms for feedback which ensures a rich database of cases from prior experience.

Advice & General

The three secrets to success in the CS are -

  1. Practice,

  2. Practice and

  3. Practice!

Keeping this in mind, we have developed methods to help you practice the patient note in a timed real examination style patient note using the patient note generator software developed by us. As you might be aware, you never fully get the complete grasp on a case until you write up the case! So, make use of this opportunity to practice and write up the patient note as soon as you are done with the case.

Partner Finder

Many test takers would like help in getting the right partner so that they can practice the CS cases. The UsmleSource partner finder program is another valuable addition that helps you find the right partner for you.

Timed Check Lists

 We use a timer that alerts you after 15 minutes for the patient interview and physical examination and 10 minutes for the patient note when you practice the patient note using our unique patient note generator software - just like the real examination. The SP check lists are representative of the check lists used by the SP's in the real USMLE step 2 CS examination.

Physical Examination Videos

A compiled list of useful physical examination videos.

Hope this unique service will help simplify your preparation for USMLE step 2 CS and make it fun and easy! Many applicants fail because of inadequate data collection. With our Mnemonic based approach, you can get the maximum data in minimum time. We use graphics to help make pages unique for so that it is easier to memorize.

Video Case Discussions (New)
