Older women, new CDL, big problems....

So I am 55 a very young 55, not scared of hard work at all, so I thought was just hired by May Trucking,in my orientation class was another woman about 3 years older,and 7 others I female and 6 men.
On the 3rs day they let 2 go ,then we all did the next round of paper work by the end of the first week we were all out on the road with mentors. I was stuck on a yard with no emenities just 2 porta pottys as my mentor got to leave because it was his home base, we had left in such a hurry that I didn't really get to bring any other things with me I only had one pair of clothes there was no showers and it was just a bad time that's not even what my concern is I concern is that when we got back and I did my "soloing out" which as you know is the testing out for all your skills your yard skills well a little trouble with my backing which that was one of the things my mentor did and didn't allow me to do and then coupling he thought I had a problem with but I didn't think I did so anyways long story short they said that I needed more training and you know areas a b and c so I went out in the yard with one of the other instructors and I was made to couple same trailer over and over and over again about nine times I believe okay and then he said we're going to do it tomorrow again until you get it and I said you know it's I got it which I did I had it down cold I did fine and then the next day he says okay we're going to do backing up so we started doing the backing up and it finally like I got it I got the angles right I'm not really good at geometry but I got the angles right I got my lineups good on what I'm seeing in my mirrors and I thought I was doing well with this okay because I know they've had people on the yard that they have trained for upwards of a month they're called holdovers and they do this well by lunch time on day two of this intense training, they let me and the other lady go after lunch stating that we were just not getting it and that they couldn't do anything else for us and yet they had a younger girl on the yard for 3 weeks until she got everything and let her carry on now does this sound like age discrimination to anyone else because I wasn't doing wrong and I would have been a model employee had they just let me you know finish my training they said you can be here for up to 3 to 4 weeks they told us that and then now they're saying that they couldn't I don't understand and then the poor woman that got fired along with me they got her to the wrong bus depot and expired bus ticket and then when I went back in cuz she called me she's like I can't get a hold of the office and I went back over there to tell them hey you guys dropped her off at the wrong bus terminal with the expired ticket well nobody even bothered to check the weather had stopped all the buses from up North so her bus was never even going to come she ended up having to buy a plane ticket to get herself home now me luckily I had my car but still I'm in a city I don't live in with no place to go and no job because we had just had signed all the paperwork you know to be saying hey you work here you know and then all of a sudden you get let go like that does anybody find this odd or is this a typical thing that happens in this industry I'm baffled and frankly a little traumatized

 

Ok, I am really sorry about the punctuation, and lack of paragraphs.
I was just wondering if this is typical, the office manager there is head of a women in trucking empowerment thing, I just thought maybe she would have fought a little harder for us to stay and learn is all....very disappointing experience to say the least.
