All F1 Grand Prix races have practice and qualifying
        sessions for the participants. The racers can take part in the practice
        sessions on Fridays and Saturdays. While individual practice sessions
        are not mandatory, it is imperative for the drivers to take part in at
        least one Saturday session. 
         
         The qualifying session of Saturdays in Formula 1 is divided into three
        distinct parts. Every session has multiple drivers on track
        simultaneously. The drivers are prohibited from stopping unnecessarily
        on the circuit or obstruct other drivers.
         
        First Part

        drop out to fill the final six grid places.
         
        Second Part
         Sixteen remaining cars run in a 15-minute session. The six slowest cars
        drop out to fill places 11 to 16 on the grid.
