  <p>Question - This function should take two arguments: exam - grade for exam (from 0 to 100); projects - number of completed projects (from 0 and above);</p>
  
  <p>This function should return a number (final grade). There are four types of final grades:</p>
  
  <p>100, if a grade for the exam is more than 90 or if a number of completed projects more than 10.
  90, if a grade for the exam is more than 75 and if a number of completed projects is minimum 5.
  75, if a grade for the exam is more than 50 and if a number of completed projects is minimum 2.
  0, in other cases</p>
