Which lesson to take?

I started skiing last year. I progressed pretty ok. I'm comfortable-ish on blues - did Bluebell, Edelweiss etc. at WP many times last year, and American Flyer at Copper is a fav. I even did Sleeper at WP and felt pretty good about it. However, I for sure want to work on my technique - specifically get completely parallel.

Gonna get a lesson or two at WP this season and I am just wondering if anyone has any advice on whether to take the BEGINNER / INTERMEDIATE GROUP LESSONS or the INTERMEDIATE / ADVANCED GROUP LESSONS?

BEGINNER / INTERMEDIATE = Whether it's your first time on the hill or you'd like to feel comfortable on something beyond green runs, any time is a good time to learn how to ski or ride!

INTERMEDIATE / ADVANCED = You're able to get around the mountain, but there's so much more to explore and enjoy with a few more skills under your belt!

Any advice appreciated!
