Once you're finished, jump onto CodeEval and work through some problems in Ruby. Find the problems that look like they're just beyond your comfort zone.
The test cases in CodeEval can be a little strange. Don't worry about the "path to a filename" code they want you to write.
Instead: For each problem you do, make a new ruby file yourself and add the test cases for the problem.
Here's an example file you can reference. In the example file, notice how we represent the sample input from CodeEval by putsing whether it == the expected output. For example:
turns into
Do the same with your challenges.
Create new files like the example file as you pick challenges to do. Translate the sample inputs and outputs like we did above.
Feel free to work through the example file first.
