Some hints for solving the exercises.

  • After cloning the repositories you can create branches on the cloned repository to recall them later and view your progress on the particular exercise.
  • Solve the different exercises multiple times and try to search another way of solution.
  • For some exercises there exists a section Further Challenges with suggestions of different ways to solve the exercise or similar exercises.
  • Use the supplied unit tests. Activate them one after another and implement the task so that the tests succeed (one after another).
  • After finishing the exercise let a more seasoned developer review your code. Alternatively use a code review site like StackExchange Code Review.
