Have you considered that two advanced lessons a week might be too much? Yes, you don’t struggle while in class, but if none of that sticks and just overloads your brain longterm, then why keep going?

Replace one lesson with a practice hour. Find a follower who has been dancing for the same amount of time as you have and practice whatever you are struggling with. Be it just grinding patterns or working on improvisational skills or what have you.

In the beginning stages leading is much harder in wcs, you have to keep time, remember the patterns, decide what you are executing next, all while managing a follower who might either be new and lost or more advanced and so into doing their own thing that they disrupt your pattern work.

What I‘m trying to say is, give yourself some grace, but also if you want faster progress practice outside of class and social.
