In most Hebrew language courses a significant majority of students are female. The only exception is the course “Medieval Hebrew: Piyyut and Spanish Poetry”, which has 70% of male students. Calling this course “the hardest” wouldn’t be very objective, but it is safe to say that the Even-Shoshan Dictionary is not very useful for understanding the texts that we read there.
In Linguistics courses i took the ratio of male-to-female students was pretty much even. The same goes for “Spanish for beginners”.
However, in the “Advanced Portuguese” course all students are male.
