Indeed. The extent of my programming knowledge entering collage was basic HTML/CSS and making and making a form in Visual Basic that swapped the positions of the "Okay" and "Cancel" buttons whenever you moused over one of them.

I knew much less than many of my peers and our school specifically had an introduction to CS class that was geared towards 0 knowledge students. A lot of the CS majors skipped it and went straight to the 2nd class, which I took the following semester.
