SC CDL General Knowledge Marathon

Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements.

Need a final study-spree? This South Carolina CDL General Knowledge Marathon is a super-challenging practice test that contains all 693 questions from our database for this SC endorsement. If you make a mistake, we’ll remember that question and will display it to you again at the end of the exam until you’ve answered that question correctly. In other words, the Marathon will cycle through your missed questions until you answer each one correctly. You must make a 100% to pass. We suggest you attempt this one after you have practiced the state’s “regular” tests, but before the “Exam”. Good luck!

I passed my hazmat test with a 100.
I highly recommend this website. They have the CDL manual, by the testee state, to read or download and a three hour video course. The video course essentially covers the same topics as the CDL manual but in more detail. There's five practice exams, marathon exam that covers all 190 questions, and the DDS hazmat simulator. There's a challenge bank that keeps all the question that the testee might struggle on.

Finished all test below 45 mins.
I tried to take the CDL knowledge test and endorsements with only reading the drivers study book from DMV and failed miserably. I had to find something quick to pass these test. I found driving-tests.org and what a great website. I played around with the practice tests and I said to myself this is just like the DMV test. So I went ahead and studied for 2 days getting 100% on all the practice tests and exams. I took the test at DMV with confidence and pass all 5 test to get my permit and the endorsements plus my real ID.

I gave driving-tests.org 5 stars….
(I wish there was something higher than 5 stars) because the program was very user friendly and I had fun learning. I started it eleven days before my written CLP (commercial learner permit) tests for Class B which included general knowledge, air brake, and passengers endorsement. I took the tests on October 25th and passed with flying colors so I now have my CLP with "P" endorsement. I had the DMV manual and it was so overwhelming to me so that is why I did a Google search for CDL tests and I found your company.

5 STARS This IS NOT Fake NEWS!
I decided to roll the dice and try to pass before then. I took my CDL exam on Feb 3rd. I also took the School Bus, Passenger and Air Brake endorsement exams. I am happy to say that i passed all the exams with flying colors! I literally got 100% on the general knowledge test. I am generally a very good test taker but I can assure you that without this website and all of the practice tests, I would have failed miserably. The CDL book from DMV is awful. You cannot read that and think you're gonna pass. Just an FYI: I tried some of the free practice tests online from other sites. They are NOT the same as the test questions on the real exam. The practice questions on this site were mostly identical to the real questions on the test. You will not regret it.
