Hi. I can also highly recommend the course. I worked through the course in about 1.5 weeks and find myself often going back to the course as I had next to zero coding skills (apart from a little visual basic) before I started the course.
Thanks to the course I am now in a position to develop my own strategies. Its been a very steep learning curve for me.
Also can recommend JCLs book if you happen to be able to read German ;-)
