What to do in refactor and retest?

What exactly has to be done in refactor and retest in module 2 milestone 3?

Just break your code into small methods of less than 10 lines and run a full build again to ensure no errors are introduced after a successful run in milestone 2.

Just dividing the code into group of 10 lines. Nothing special?

Nothing special at all. Just ensuring all methods are of 10 lines and the code still works.

For example in my mainreadquotes i have 20 lines of code. Then what to do?

Break it down into two or three methods. Have mainreadquotes call 1-2 helper methods which perform a subtask and return value to mainreadquotes.
