   USMLE STEP 3 Preparation Plan:
   
   1. Start early
   
   Different preparation times have been suggested, Depending on what you are doing, if you are in residency or not, at
   least 3-4 weeks of dedicated studying for the exam is needed.
   
   2- Q Banks:
   
   NBMEs can be used as a way of predicting your final score. Take an NBME at the very beginning of your Step 3 study
   period. Doing this can give you a baseline score, and will often make students much less nervous about the exam.
   
   2. Consider using tutor
   
   Live tutor can save a lot of your time reviewing your weak points whether they are ccs, biostats or pharmacology. that
   will allow a more focused approach to your studying.  
   
   3. Master Clinical Case Simulation (CCS) Questions
   
   CCS accounts for 25% of your final score, before going to the exam, make sure that you practice the cases and you
   understand the principles about the software
   
   4. Don’t underestimate Biostats, preventive medicine, Abstract/ pharm ads and pharmacology questions
   
   The exam had a significant number of biostats questions, more than prior steps. These topics are as important as
   internal medicine and pediatrics in the exam.
