USMLERx has already been battle-tested by thousands of users. Here’s what people are saying:

• “I used USMLERx and thought it was incredible… I scored 99 on the exam, which I largely attribute to the First Aid book and USMLERx. Keep up the good work!!”
• “Wow… USMLERx is badass… USMLERx was challenging and required secondary and tertiary analysis (2-step or 3-step thinking)… this is more representative of what the real test is like.”
• “I own Kaplan Qbank as well and completed most of it… but I heard so many good things about USMLERx that I just bought this and I love it! The explanations you provide are awesome compared to Kaplan Qbank.”

We are currently looking for talented students with an interest in medical education to be involved in First Aid and USMLERx projects.

This is a great opportunity to learn about the authoring and publication process - great experience if you ever want to publish a book of your own someday. You can even receive publication credit and a small stipend too! The time commitment is minimal to moderate and fairly flexible around your schedule.

Ideal applicants are those who are enthusiastic about teaching others and who have a keen eye for detail and the written word, a good working knowledge of Word and Adobe Acrobat, and you must have Internet access.

If you think you might be a good fit, we invite you to find out more. To let us know about your interest please email us at firstaidteam@yahoo.com and be sure to include the following: A current CV, your school, what year you are currently in, date of your USMLE Step 1 exam, date of your Step 2 (if applicable), and the reason for your interest.

We look forward to hearing from you.

The First Aid/USMLERx Team

We at the USMLERx team have one singular goal: to continue to improve both the quality of questions in our question bank and the manner in which those questions are presented to you. With this in mind, here are some exciting new features on our Web site that are sure to enhance your board preparation experience:

1. Half-day or full-day exam simulation. Now you can simulate an actual half-day or full-day exam on USMLERx.com. You can create either a partial simulation, with four blocks of fifty questions per block, or a complete simulation consisting of seven blocks of fifty questions per block. (To do so, you must have enough unused questions in the bank to create these simulations.) Once questions are placed in Simulation Mode, they will not be available for regular test use on the Web site. As with regular tests on Step 1 Qmax, you will have the ability to continue after each block or suspend the simulation for later. Each block in a simulation will have a separate Analysis Page, and at the completion of each simulation, an Overall Analysis Page will be available for your review. This new feature will allow you to track your progress.
2. Review Question Page. The questions you annotate for review will now be listed on the Review Question Page with links to the actual questions. All you need to do is click on the date link next to a given question, and a new window will open with your question(s) for easy review.
3. More specific options for creating tests. You can now create a test with both an organ system and a discipline, making testing more defined. We have also focused the correct/incorrect question use. You can create tests using ONLY incorrect questions. Watch your incorrect question count go down as you get each question right!

We gave USMLERx a major upgrade this Monday:

• 1,400+ significantly revised Step 1 questions and hundreds of minor updates.
• All question explanations now integrated with the high-yield facts from 2008 First Aid for the USMLE Step 1.
• The high-yield facts now tagged with a page number for easy referencing back to First Aid.
• Hundreds of new questions coming online this week.

Rationale: Medical students have few validated predictors of USMLE performance. We hypothesized that USMLERx Step 1 Qmax could predict USMLE Step 1 performance.

Methods: In this prospective cohort study, 26 U.S. medical students who used USMLERx for USMLE preparation completed baseline questionnaires regarding their performance on USMLERx, Kaplan Qbank and the Medical College Admissions Test (MCAT). All questionnaires were completed within one week of participants taking their USMLE examination. Participants subsequently reported their 3-digit USMLE Step 1 scores when they became available. Spearman’s rho and single linear regression modeling were used to assess associations between variables.

Results: See table below. Participants had higher than average scores for the USMLE Step 1, MCAT, and USMLERx. USMLERx scores strongly correlated with USMLE scores. Kaplan and MCAT scores had moderate correlation. In single linear regression modeling, USMLERx, Kaplan Qbank and MCAT scores were highly significant predictors of USMLE performance with high T-scores. USMLERx scores were able to account almost 80% of the variance in USMLE scores.

Test	Mean score (SD)	Correlation (Rho)	T-score	p-value	Variance (R2)
USMLERx	68.9 ±7.7	0.89	7.95	<.001	0.79
Kaplan	67.6±7.2	0.76	5.17	<.001	0.67
MCAT	31.7 ±0.5	0.73	4.80	<.001	0.59
USMLE (3-digit)	234.7 ±19.8	–	–	–	-

 

Conclusions: USMLERx, Kaplan and MCAT scores appear to be significant predictors of USMLE performance. In this sample, USMLERx was highly correlated with the USMLE Step 1 performance and was able to predict approximately 80% of the variation in USMLE scores.
