The best way to learn programming is through practice. There will be weekly programming homework. All assignments must be committed to github with a pull request by the specified deadline. You may work in pairs to complete these assignments, but if you do, make sure to have each person commit a solution to at least one problem. Working in a pair will earn you +2/100 points. It is in your best interest to understand the solutions to each problem.
Assignments will be graded with the following criteria:
