No matter how much money you spend on books, every medical student needs to do a ton of practice questions for the USMLE Step 1. Questions are an excellent way to learn the useful tip-offs and keywords, and—depending on the source—get a better feel for the board format. They’re also a form of active learning, unlike trying to self-induce a coma with the universally-utilized First Aid for the USMLE Step 1. I believe USMLEWorld is the best question bank out there—despite its draconian efforts to prevent IP theft—and there is no free source out there that matches it (especially for the final marathon push before the big day). That said, there are other ways to study, especially during the basic science years.
For question books, post-Step MS3s and your local Half-Price Books are always good resources to buy study materials on the cheap. But free is better, and the internet is undeniably convenient and portable. I scoured the web to find free question banks online (updated February 2013):
- The NBME offers its own small set of free practice materials for the Steps 1, 2, and 3. You have to download the program here (22mb), Windows only. It contains the software that the actual Step uses (Fred V2), a tutorial, and 100+ question practice test. A must do. A pdf file is also available from the above link, which contains the same questions and is a little more accessible. Kaplan has the answers/explanations to the old version available here.
- USMLEQuickPrep is a large (~4500 questions) and entirely free qbank. It’s the largest and most exhaustive free source out there. The questions are a mixed-bag, and not all are in Step-style, but most have explanations, the site isn’t too clunky, and it certainly stands out for its sheer volume.
- Lippincott’s 350-Question Practice Test for USMLE Step 1 is a solid Qbank, but you must register (for free) before using it.
- MedMaster (makers of the “made ridiculously simple” series) has a USMLE Step 1 qbank (among others). The questions are not step-style but rather content review. It’s a good foundational accompaniment to book learning, as it clearly highlights key facts and distinctions that are crucial for the Step 1, but it does not prepare you for the exam proper. There are also no puns or goofy diagrams like the book series.
- Test Prep Review has a USMLE practice self-assessment section. There are 20 modules of 20 questions for 400 questions. They’re mainly fact-recall and not vignette-based, but it’s easy to use and accessible.
- Wiki Test Prep [now defunct]
iswas a student-written qbank with over 900 questions with explanations. The site is great, and you can browse questions by keyword, flag questions, and create your own tests. It also lets you know what percentage of students answer the question correctly, which is interesting. The questions are in clinical-vignette board format.
- 4tests.com hosts the 60 question Kaplan diagnostic exam. Answers can be exposed during the test if desired and do contain explanations. (Mom MD also has the identical sampler, only organized in six 10-question pages with answers directly below questions)
- ValueMD has a large question bank divided up by subject. The site also requires a free registration. The questions are straightforward fact-recall type and the site itself is clunky and hideous, but it’s still decent review.
- Kaplan lets you try one 48-question section for free after signing up.
- USMLERx has a free 20 question qbank test using the NBME’s Fred V2 software. Their “Qmax” qbank is made by the same people who wrote First Aid, and so the explanations come straight for the book, which is a serious shortcoming in my opinion.
- USMLE Consult has small free sample trials for both Step 1 and Robbins Pathology, which are both relevant.
- Learntheheart.com has 50 cardiology USMLE Step 1 questions, with plans to add more.
