Intro CS classes turned into highly intimidating environments where the males had significant computer experience and may well have spent several years programming already

When I started my first year of CS at uni, I had almost no experience programming and I definitely felt intimidated by the (many) fellow students who already had 5+ years of experience.

During one of my first labs, I was told to write a toString method for a Java class. I could not understand why the signature had to say "String" twice. A TA spent half an hour trying to explain it to me and eventually gave up in desperation.
