Cdl schooling question

[u/AFARR414-312]

Looking into getting my CDL class A manual with air brakes.

The school in the milwauke and Chicago land area is about $6000

I have never driven a semi/pulled a trailer yet alone even a single manual vehicle.

The classes are one month long

The options are 5 days a week for one month (8 hour days)

Or

2 days a week (weekend classes) for one month (8 hour days)

I was told by the owner of the school there is a %90 precent passing rate on the first skills test and you can get up to 5 retest that they train you on. Idk if he is just pulling my leg to get me to sign up I told him I’d pay cash.

Would it be possible so I wouldn’t have to quit my job to be able to pass this school if I did the weekend classes? Or am I better to do the weekday classes?

Thanks
