I would say you're screwed.

Here's some advice, focus on the 30% of each of the 5 area's you need the most to do something with. The rest is just noise right now.

Usually my personal process is to spend 70% of my time on one area in particular, picking up the others as I need to learn new information for what I'm working on at the time. But that doesn't seem to be an option for you so well, good luck.
