How hard are upper level Spanish classes?

I am a senior, I took ~11 years of Spanish growing up. Half of my day was in my Spanish as a kid. I took AP Spanish and concurrent enrollment Spanish in high school. I haven’t taken Spanish in ~4 years but today the class I was going to take to fulfill my scd-as requirement got cancelled. Would it be doable to take SPAN 3620 or SPAN 2235 pass fail? Any other reqs for easy scd-as classes would be appreciated
