Not all of the material below is directly related to
certification tests, but anything that tests your knowledge can be
useful in preparing for exams. I think it's also fun just to self
test, even without any intention of becoming certified.
By the way: when using search engines to find sample exams, be
sure to try different keywords: "linux certification tests", "linux
sample exam questions", "sample tests", "certification quiz", "free
sample tests", "sample exams", etc. You won't find everything out
there unless you do.
These are other resources, free and otherwise, for testing your
knowledge of Unix and Linux or preparing for certification
If you have certification resources that you would like listed here, just let me know. If you'd like me to review your site, write to me about that. I'll require an account for at least a few days and can only promise to be honest in my opinions.
