You can get/understand advanced concepts, after working on 3-6 months. You can get one whitepaper (silk reviewers guide) from segue. It gives outline about advanced concpets of Silktest and test automation.
You also can take advantage of Segue's online training for SilkTest. Here is a link to the schedule. By clicking on any of the course names you will be able to read a summary of the course content. http://training.segue.com/main_courses.asp
With online training, you don't have to travel and you can work on the course materials for up to a two-week period. You also have an instructor overseeing the course throughout the course duration.
I have some good news for you - the Advanced Testing with SilkTest course is also coming online; I should have mentioned that in my original post. The timing for it is not until much later in the year, though.
