Studying for Category B theory exam in English

TL;DR: Are there any online textbooks in english, that include obscure topics that might show up on the drivers test? Or, are there any online PL books, where I could click on Chrome's "Translate to English" feature in real time as I read it?

I've done 30 hours of lectures, and I've been studying for the driver's theory test using prawo-jazdy-360.pl as they have an English option. After doing 12 practice tests, I've passed 4, with my average test score is a 61/74 right now.

I'm lacking in knowledge for certain questions, i.e. first-aid. For example, I will get a question like, is the gold or silver side of a warmth blanket the warmer side? This info was not taught in my 30 hours of lectures, and can't find it in the (kind of lacking) eBook or Lecture section of the prawo-jazdy-360.pl platform.

And when a question like this shows up, I can just learn it on the spot via the explanation box. The problem is, I imagine there is some textbook chapter that includes topics like gold/silver blankets, that also includes other topics, which may show up on the real test – like whether a powder fire extinguisher can put out a type B fire (which is another thing that showed up when doing practice tests that I got wrong).

I've looked for EN drivers books, and the only thing I see show up is GRUPA-IMAGE. If they had an online version I would pay for it, but I don't want to wait a week for it to ship here, I might decided to do the theory test in that timeframe.
