Signature-50 class as first class advice

I've been hearing about solidcore for a while now, I did one class like 2 years ago and I really struggled but recently I wanted to try again so I booked a Signature-50 class before I realized that there's a starter 50 class, and since I already booked so there's nothing I can do about it, so does anyone have any advice for a beginner going into signature-50
