After finishing their Ruby course and being thoroughly impressed by the structure, the explanations and the overall approach to simplifying Ruby, I signed up for their Rails course and the Blocks and Iterators course. Just started Rails, it's a lesson you don't rush, so taking it one lesson a day. The reason it should be taken slowly is, like with their Ruby course, there are parallel projects happening while learning. That is, they teach using one app, and ask you to do another app using similar methods, so you need time to digest the information and apply it to two projects. If you have an idea for another app, you can start off on that as well. 
Meanwhile, I'm on their Blocks and Iterators course, which again deconstructs the topic beautifully with interactive, engaging diagrams/animation drawings. I take a screen shot of these drawings for future reference, like a ready reckoner of sorts.
Again,I keep wondering how did I miss this course? I remember seeing it while searching for online Ruby courses when I was caught by the coding bug, but for some reason didn't sign up. I am on Treehouse, Udemy and Tealeaf for Ruby, Rails and other courses but I strongly recommend Pragmatic Studios as the first step. I've also started re-taking the Ruby course, as a refresher, to relook at the concepts and see how I can apply them to say, a problem on Tealeaf. 

I just finished the Pragmatic Studio's Ruby course. They give you a timetable which lays down a one month long plan to take the course but I finished it way ahead. Because it was so simply and beautifully explained I didn't want to stop at just doing one segment a day. 
Mike and Nicole have an excellent way of teaching a complicated language to beginners. First, the diagrams. Important aspects of the language are explained with simple diagrams that visually deconstruct the point, making it easy for you to understand the concept. If you want, you can take screenshot for future reference.
Second, the tete-e-tete between Mike and Nicole. They've mastered the art of two people teaching a lesson at the same time which is a difficult thing to do (there's a Udemy course on a different subject where the teachers of that course try that but doesn't work). Here, Nichole and Mike take turns at asking the relevant questions and raising important points and answer them. 
Three, the whole layout of the course, from strings and numbers to coding three apps. They code a movie app while you are asked to do a game app while there's a bonus coding opportunity for a crowdfunding app using the principles taught in the course. 
The TDD segments are a bit tough, they are more like your afternoon math classes, a pain but necessary. I skimmed over the TDD (Test Driven Development) sections but will have to go back and learn them. In fact, I've already re-started the course as practice is essential in learning anything new.
Towards the end, a couple of points tend to get rushed but that's nothing big. I've signed up for their Rails course and am going to take up their Blocks and Iterators course today. 
I can say in all honesty that if you are a beginner or coding enthusiast looking for your foray in Ruby, this must be your first stop.
