Profile For Jai Tee

I'm having trouble with parallel parking,blindside and alley dock.

I'm in desparate need of someone's advice. This is my 3rd week in CDL training at the tech school in my hometown and I can't grasp some of the maneuvers.My instructor told me that he may have to drop me from the course because I have not gotten some maneuvers right before going on the road in two weeks.My question is if I am dropped from the class what other options are there left? I work a full time job and my permit will expire in February. If I allow that to happen I will have to go through the testing process all over again. My instructor advised that I could come back for Winter semester and take that portion again but it will be cutting pretty close to my expiration date. Any advice ya'll got for my situation will be helpful. Thanks!
