I got my CDL about 5 years ago, using the driving school at the community college in Springfield-- it was a lot cheaper than Roadmaster and such. The test wasn't bad-- like others have said, remembering the important parts of the pre-trip was the hardest part of it. Although the whole thing would have been easier if I hadn't taken the damned thing in the snow. The parallel park thing was kind of a pain, too, but not earth-shatteringly so. As for the written test (which you only do for your temps, if I recall right), it was really easy. I did the main test, doubles/ triples, hazmat, tankers, and air brakes in like an hour total.
