Q: Informix Courses vs Manuals

Hi, We just recently got a SE/4GL pacakge and I'm looking into the education courses offered by Informix. I've read a bunch of stuff from the manuals that they sent and am working through 4gl by example. I've created a database and populated it as well - and have run various interactive SQL commands on it. SO, my question is, is it worth taking the following courses? Relational Database Design Structured Query Language Developing Applications Using INFROM<IX-4GL INFORMIX-SE Administration Advanced INFORMIX-4GL Development My feeling is that I can skip the Advnced 4Gl course until I start doing a lot more complicated kinds of things. I looked at the description for the Databse and SQL ones and they look pretty simple so I figure I'll skip those too and just take the Developing ... 4GL one and the Administration. Can anyone compare the courses to the manbuals shipped with the software? Thanks Marc marc@mail.pamco.com (different from the above address)
