How to use these worksheets

  1. Pick one skill that matches the lesson or the gap you have found. Open the pack page first if you want to check the level and length before using paper.
  2. Print the PDF and set a clear stopping point. A single focused A Level Computer Science sheet usually gives better evidence than a long mixed booklet when you are checking whether one method is secure.
  3. Mark it with the scheme at the back. Keep the questions that were missed, write down the reason, then return to that skill with a new pack instead of repeating answers the student already knows.
See the method: Structure and Function of the Processor

A processor has a clock speed of 2.5 GHz, and each instruction takes an average of 5 clock cycles to complete. Calculate the number of instructions the processor can execute in one second.

  1. Convert the clock speed to hertz: 2.5 GHz = 2.5 x 10^9 cycles per second.
  2. Divide the cycles per second by the number of cycles needed per instruction: 2.5 x 10^9 / 5.
  3. Calculate the result: 2.5 x 10^9 / 5 = 5 x 10^8.
  4. Final answer: the processor can execute 5 x 10^8 (500 million) instructions per second.
