It won't hurt to study the agile modules in a different order, if you think you would benefit from learning that information now. Why not give it a go? You can always refresh yourself on agile principles when you reach those modules again.
I am currently in the begining of PrepCast lessons (just finished Module 4 (Integration). However the quizzes include a lot of Agile questions and I am getting low grades because I didnt study them yet. Do you advice I jump to modules 20 to 22? And later resume at Modules 5 to 13?
