Updated April 12, 2016. These days you may need just a tetanus shot, or a vaccination against tetanus, diptheria and pertussis. Tetanus is a bacterial infection of the nervous system, also known as lockjaw. Symptoms include muscle stiffness, difficulty swallowing, muscle spasms and seizures.
The average MCAT score each year is somewhere around a 24 (8 in each section). A good (competitive at most MD schools) score is around 30 and a stellar score is somewhere above a 34 to 36 (competitive at the top medical schools in the country). A score of 36 or better would put you in the top 2% of the country.
What is a good MCAT score? Currently the average MCAT of students who actually matriculate at medical school is 31. 31 is roughly 83rd percentile. Nevertheless, keep in mind that this is an average. Applicants with scores greater than 31 get rejected and applicants with scores less than 31 get accepted. Generally a 33 is a safe score while anything above 35 would be considered a great score.
