CodeMastery Test CI3.0

Another BIG reason is in my personal programming experience I always look at the documentation.
Which will really waste time. So why not try to remember these codes as many as I can.
This way it will save me time.

Understanding the coding concepts will save you vastly more amount of time than memorizing how to write a controller in a specific framework.

Just my 2 cents. Good luck.

Codeigniter is simply one of the tools you need to learn to be a successful developer. Always add more tools to your coding arsenal!
