For me it's challenging because I have no background in CS or programming. But using Google and other online resources has helped me improve. Some challenges are more math based too so that adds to the challenge for me.

You will develop good problem solving skills because after a while you will find yourself re-reading the instructions so you understand the root of the problem.

There are a lot of skilled people here so look at their code to see how your solution compares to theirs and also if you understand what they were doing and why. Enjoy!
