Hey Rushad61,

Thanks and I'm glad you found the site helpful.

As far as other sites go I didn't find any other sites with great practice questions, however there is a lot of great study material out there.

A post above I listed my newest study track and the stuff I will be going over again prior to my up coming re-write

Also there is a good course on Pluralsight formally TrainSignals by Scott Lowe which is good.

Aside from that focus on the sites to go over the blue print in good detail and cover everything that is in the blue print as anything in there is fair game.  Also make sure you have a strong understanding between Conceptual, Logical, and Physical Design.

If you have any questions or ideas you ever want to bounce off me feel free to post here or PM me.

Cheers and the best of luck with your DCD!
