Texas CDL ,

CDL for Texas.

To get right to it, Yes the materials provided in this app will greatly help
You gain the knowledge needed to pass your written test. NOTE- some questions WILL be worded slightly different in comparison to the test your gonna take out your local DMV. Some questions I had to read a couple times and re-word in my mind to make it make sense to what the app had me studying. Also my last Note THAT HAS NO RELEVANCE TO THE APP. Once you get past your written test congratulations your half way there, but the hard parts just begun I wish I had an answer as to why Pre-Trip inspections are so hard but I don’t These people at the testing facilities are down right ignorant, you go to one they tell you didn’t pass and will not tell you why (because it’s considered coaching) is what you’ll be told. And if you go to another facility you may be told your not passing today because you’ve been told to study the wrong material. So in my opinion Pre trip is based on what prompter you get that day,there opinions on what’s right and the mood there in. Took me 7 months to finally pass everything from the time I took my written test to the time I passed pre-trip,skills and my driving. So mentally prepare your selves for what’s to come. And good luck out there.

Congratulations🎉 and thank you for your detailed review! That is very normal for the questions to be worded slightly different, but if you review the app thoroughly and carefully read the question, you will no problem selecting the correct answer on your real exam!

I purchased a well known book from Barnes&Noble and ended up finding more than one mistake and incorrect answer from their “correct answer key”. Then, instead of continuing with the book, I used this app casually for two weeks and I ended up passing 6 tests in one day on my first try. The mandatory 3: general knowledge, air brakes, and combination vehicles tests. Plus, because I was well prepared, I ended up taking 3 endorsement tests on the same day: tankers, doubles/triples, and hazmat. I did purchase the full version of the CDL GENIE but I still saved money because whatever endorsement tests you take when you get your permit and you pay for you CA CDL, the usual cost of the endorsements are included free in the regular base CDL license fee of $78. Meaning, If I went back to the dmv after I got my license, it would’ve cost me $46 extra to get my endorsements added on. It is well worth it to use the CDL GENIE.

I've never paid for an app

I was hesitant about paying this much for an app, but after doing the tests several times in order to prepare myself I can honestly say I feel pretty good about the $15 I paid for the app. If there is a better/cheaper app out there that is as helpful and accurate I'd be impressed. Bottom line is this app will definitely absolutely 100% guarantee you will pass the written test. If you pass the tests on the app you WILL pass the test at the mvd/dmv. Just pay attention to wording on the actual test because some of the questions were similar, but worded differently. If your state allows, use the "skip" feature on the test if you're not 110% sure of an answer. Answer the questions you are 110% sure of first and you might not have to answer the questionable ones. Good luck.
