Permit Test Tips For Remembering PSI

I'm training for my CDL permit and for some reason my brain can't remember the correct PSI for single vs combination, with vs without service breaks applied, etc. etc.

I understand the cut-in / cut-out numbers, etc. (anything that is different enough from each other) But the ones that are close in number are throwing me off. I'll think I have it memorized, then I fail the online practice tests questions.

Now I'm thinking of making flash cards at this point so I can hammer the information in. BUT... I also thought I might ask you all if you have any memory tips or anything that helped you remember them for testing.

Any clever things like "I before E" sayings out there for this topic?

Thanks!

There is no substitute or better response to your post: High Road Training Program

Yeah, that's the prep test on which I failed those specific questions.

I'm using that and I agree it's the best out there... better than the DMVs offered stuff... better than the one recommended by my recruiter in their prep packet, etc. — totally agree with you. They actually knew about this site and were glad I was using it.

I know I'll eventually get it, because I'm getting all the other stuff. Just thought "maybe" this specific PSI part, someone had a random "teaching tip" they may have used in addition to basic memorization. An additional association of some kind I guess.

Like I said, I'm sure I'll eventually get it. Just thought I'd ask in case anyone else had a similar issue remembering these and had a tip.

Guess I need to make some flash cards and hammer it in my brain.

Flashcards worked great for me. I put pre-trip questions on one side and the answer on the back. I'm proud to say when I tested out the examiner said I did the best pre-trip he has ever seen. There's a lot of info that needs to be learned and sometimes repetition is the best way to cram it all in. :)

So quick update... I made some flash cards. This info in particular was hard for me to log away because I had no visual reference in my head to attach it to... if that makes any sense.

I made a flash card for each possible version of vehicle/psi/brake setup. And now that I've been looking them over, something actually clicked as a visual for me to reference in my head. (The paragraph in the CDL book didn't click with me)

So now I can say "brakes applied or not" and cross reference that (visually in my head) with "vehicle type" or "psi" and tell you the other.

I know this is a strange "small item" that someone else might just remember with no issue. But now I can also remember it.

1 2 3 2 3 4

Service and air brakes released

1 single vehicle 2 psi per minute - breaks off 3 psi per minute- breaks applied

2 combo vehicle 3 psi per minute - breaks off 4 psi per minute - breaks applied

I may have written down wrong, but the 1,2,3 and 2,3,4 worked for me.

Yeah... 123 / 234 is pretty clever. Thanks.

Sounds like you got some good answers, but I'll add my 2 cents anyway: start with 2, if you have a combo add 1, if the brakes are applied add 1.
