I am seeing a lot of material on the forum with regard to Spring 3.0 Certification Exam, but I don't think I found any for Spring 4.2.
Has anyone here done it and can you recommend the best subject material to study?
I know everyone references jeanne boyarsky's notes as being useful but are they outdated for this exam?
I'll recommend the actual course, with the provided course notes and lab exercises. It's expensive but far superior to most other courses as its provided by the actual Pivotal developers who work on spring framework. I found that the exam had a lot of subject matter which you needed to have a good understanding of. Some parts of the framework covered are not always used by the average web developer.
I've seen a certification book advertised, no idea if it is any use.
