Having trouble finding exercise related to Civil Engineering/Surveying for CAD software? Are there any websites, software, books/dvds, forums?

So I have an AS in CE Technology with some certificates in CAD. Its been a while since i have been to college and was seeking some practical training for Civil/Surveying Projects so I can really fortify my CAD awareness. The CAD tools are fairly easy to operate but I would like to be sharper in application of the software related to constructing plans, surveying calculations on software, cut/fill practice, blueprint standards, creating accurate profiles and construction drawings, etc. Is there a website that offers these types of exercises or a book/dvd, or even software with tutorial projects? A website or dvd with a large scale civil tutorial would be very helpful. College was a very fast learning experience and the lessons were just an introduction to the project fundamentals. I have worked in a civil engineering office and learned that it takes much more than advanced CAD knowledge to work with engineers in achieving project standards. So it would be nice to have a mock-project to really practice repetitively to understand the type of results a job of that caliber would demand. Thank you.
