LPT: Use online videos to study for subjects like math, physics or any other subject that requires understanding formulas.

My degree requires me to pass subjects like system engineering, hydraulics, thermodynamics, economics, statistics and more subjects that require math skills. I don't study that well with books, but having a good teacher helped me from time to time. There are lots of them out there that have dedicated video lectures where they explain something that you can rewind at any time. It has helped me immensely to the point that I couldn't have done it without them, even the Englisch ones (I'm Dutch). Youtube has always been one of my favourite ways to procrastinate and the online lectures had such a low threshold, that it was an easy way for me.

For some people it works, for others, it doesn't. But if you're stuck, this may just be that one trick that can get you to pass your test.
