In my entire high school (2500+), only 3 current female students have taken or are currently taking APCS. My twin sister and I took it last year. It was really hard being in such a collaborative course when my classmates would freely share code and work with each other leaving me to figure things out by myself.
My former CS teacher made no attempt to recruit girls into his class. I went to his class the other day so I could find more female coders for an all-girl hackathon. I sadly find out only one girl signed up this year. Last year, girls made up more than a third of the class. Our team will be the smallest by far.
