Why pay 4-digit $$, as it is said on the site, for courses when you get more out of it with just $139?! This would be the only bootCamp on Java technologies if I would ever be asked for recommendation. Sir Mr. Shin rocks!!

I had been away for a year or so, but now I am back. Glad it did because reading a book and trying things on your own is one thing, but the codecamp interaction at JPassion.com is excellent!

Groovy/Grails codecamp took me from zero to functional in a short period of time.

Great course which tackles lots of concepts, each explained with examples in the labs. Basically, it's so well described that you can't get lost through the exercises and you can learn and review the material on your own afterwards. It's quite dense and sometimes fast paced but as I said, you have the material to review everything anytime.

The jpassion Grails code camp was the fastest solution to learning how to develop applications in Groovy and Grails. The cost is the lowest anywhere!

Thirty years ago, I was introduced to a similar framework to generate webpages, EasyScreen. It was sold that all apps are the same and it would reduce number IT developers. Center stage comes Grails, which aids for smart apps and smarter developers. Make apps clean, clear, concise code and add intricate updates. Sang Shin brings the students thru the clarity and sophistication of Grails. An intense course starts for beginners and builds Grails experts.

The codecamp and your online courses are great. I like the way you have covered more complex areas of Groovy and Grails as well as the basic things. It is much better than a Groovy and Grails course my company sent me on, which costed $3000, and I am learning more from your course.
