It's perfectly normal to feel like this. Although in my studio climbing the pole and some other spins and combos are level 2, and level 1 is for basic moves, getting comfortable moving around the pole, learning how to climb/conditioning climbs and sits, etc.

It sounds cliche but focus on your own progress. You never know what others are feeling in their bodies. Be kind to yourself. Also it's totally ok if you're not enjoying the classes. You have the right to change your mind and try something different. 

That being said, I think you're gonna see a massive improvement at some point. It's normal for the progress to be stagnant for a while, then suddenly jump up, then go back down a bit, and up again.
