If you have never touched programming in web development, it might be a bit hard to cover these topics with the goal of "being a ready web developer", but passing exam is not that hard in this subject.

For those already who have experience in web development, your only problem might be last two chapters - AJAX and PHP. Everything else could be easy.

If you are new to this and want to actually learn web dev, I have made a chapter dedicated for you - for exam it is not required. For those you just want to get over this subject, try to spend time roughly like this:

HTML and CSS - 20%
JS - 30%
AJAX and PHP - 50%

If at any point on watching the dedicated chapters videos, you feel that there is not much time left , then just checkout Ashish's Oneshot playlist and See Roshan Bist Notes.

I want to emphasize on JS and PHP not because they are hard, but because they need time to be familiar.
