Credit deficient in electives?

I'm a Junior in high school, i screwed myself my freshman year, long story short is that I'm going to be .5 elective credits off from meeting the graduation requirements, what are my options? will i have to take another semester of high school to make up .5 credits? My school offers credit recovery but the only classes it offers are "core" classes (i.e. math, lit,science ect).
