I feel demotivated after my 2nd class

Yesterday I had my second pole class. It's a beginner course, but it's not one of those 6-week courses. Instead it's an open class which means that the participants are different each time. Yesterday there were a lot of people who had been doing it for several weeks or months. For one person it was her first class.

Firstly, I'm missing a bit of a structured approach. The teacher said something like "What are we going to do today? Ah, let's see". So I don't feel like I'm learning the basics in a structured way. We started with a fireman spin and then we were supposed to climb. It was the first time for me. I'd say I'm an athletic person, I do weight training and yoga several times a week. She showed it and then we should do it on our own. But it was impossible for me. It was really slippery, I had no grip at all. Most of the experienced people had climbed before, so it wasn't a problem for them. I felt really bad.

Is it normal to start with moves like that? I didn't think it was very beginner-friendly, but she didn't mention that it was an advanced move. Instead she acted like everyone should be able to do it.
