  Study suggestions
  • Do the previous final exam in an exam setting after some serious study.
  • Work in study groups to help each other out in preparation. Give each other problems to do in an exam setting. After doing the problems alone, critique each others answers.
  • You will want to work out small examples of both encoding and decoding for all the algorithms we have covered.
  • Review all the solutions for the weekly assignments to make sure you understand them.
  • Review the midterm solutions to make sure you understand them.
