USMLE Registration

USMLE registration is done for any MD from USA or Canada. The medical student from any other foreign nation whose institute is a part of international medical directory is also eligible for registration.

There are limited number of seats for each testing date and seats often fill up quickly so applicants may wish to apply for a testing date as soon as possible.

USMLE Step 1 Kaplan classes


There are a lot of coaching institutes training for USMLE Step 1 exam preparation. Some USMLE coaching classes also provide books and materials directly for sales. A lot of CDs are available for learning at home. They are very helpful sometimes when you are preparing for USMLE. But not all the CDs and material available in the market is useful. Sometimes it is mere waste of time and money.

Hence, one must be very alert in selecting books, materials, Dvds etc for USMLE preparation. The most famous and reliable classes for USMLE Step 1 is Kaplan at present. However all have different views and experiences. So both type of views exist among the medical students regarding any coaching class or material. So it is upto the individual to decide which class or material is good for him.

Answering Strategy USMLE Step 1

Strategies for Answering Single One Best Answer Test Questions In USMLE Step-1

  • Read each question carefully. It is important to understand what is being asked.
  • Try to generate an answer and then look for it in the option list.

  • Alternatively, read each option carefully, eliminating those that are clearly incorrect.

  • Of the remaining options, select the one that is most correct.

  • If unsure about an answer, it is better to guess since unanswered questions are automatically counted as wrong answers.

USMLE Step 1 Test Question Format

Single One Best Answer Questions

Step 1 includes only single questions with one best answer. This is the traditional, most frequently used multiple-choice format. These items consist of a statement or question followed by three to eleven response options arranged in alphabetical or logical order. A portion of the questions involves interpretation of graphic or pictorial materials. The response options for all questions are lettered (e.g. A, B, C, D, E). Examinees are required to select the best answer to the question. Other options may be partially correct, but there is only ONE BEST answer.
