A Level Computer Science
   • Computer Science is the study of the principles 
    and use of computers and- “Computational 
    Thinking”
     –This involves problem-solving skills and techniques 
      that engineers use to write programs and apps. 
     –Examples of these techniques are
       • breaking down complex tasks into simpler components
       • algorithm design
       • pattern recognition / generalisation 
       • abstraction.

                                     Rules:
      •  The problems come in three levels of difficulty: A, B and C.
         The "A" problems are the easiest. "C" problems the hardest.
      •  You can find a problem's difficulty in the problem overview 
         before you click on it.  The difficulty of a problem determines 
         how it will be scored.
      •  The scoring rules are as follows:
