Ballet: confused whether I should move myself to Elementary level?

Ok I've been doing a beginner's ballet class for around 6/7 weeks now, and unsure whether to move myself up as it's kind of getting repetitive. Throughout the whole lesson it's just work at the barre which I know is COMPULSIVE, but we only ever dance for 3 minutes at the end.. I thought Elementary would be to much but I've just seen a Beg/Elementary class which I think would be a good transition? Should I go for it? I know most of the positions but even if I didn't I could just copy the other people? The classes I go to are open and relaxed without grades so they don't tell you whether to move up or not, only thing I'm not too good at is stretching but I think this would improve?
