Is the curve better during busy season?

I've been wondering this. For some reason, I feel like I do the same sometimes and my score is 10pts higher during January-April vs when i take it in the summer. I still failed FAR and audit, do you feel like its becacuse everyone is stressed out. I'm thinking about taking a break and studying and trying to take it during busy season because I have a more niche role and our busy season is september-october
