Is there a reason its start with CS253 then flies back to CS101 in section 3. My prior understanding was CS101 knowledge is required for CS253 to make more sense. It seems to jump around a lot aside from adding additional resources to help learning during specific sections.
My apologies if you found that disorienting! You are right that CS101 becomes a prerequisite for CS253 (if you don't know python already). The reason I started with CS253 is because, personally for me, it helped a lot to know the top level concepts of "How web works" and the front-end (because that is what a normal user sees) and then go into concepts of server side languages which might seem too involved and dry to a beginner.
