To be blunt. You got one third of a multiple choice paper wrong. This is indicative of the fact that you have a very weak understanding of what is a fundamental subject, and haven't put in the requisite effort.
I doubt that the answer is in finding ways to make the subject easier for you.
Go back to basics. Get the study material out and learn the subject.
You haven't "mostly" got yourself to blame for this. You only have yourself to blame for this.
It isn't the end of the world, so dust yourself down, and put aside the time, and make the effort to learn the core subject.
This is in the "wannabes" forum, suggesting that is your own ambition. These exams at CPL/ATPL level are not going to get any easier or more entertaining. Career professional pilots are also expected to digest an almost daily diet of often very dry regulatory, legislative and operational changes.
If this is your goal, you would be well advised to stop making excuses or finding reasons why you cannot learn. Start adapting to what is required, and put in the necessary effort. It is a very very competitive environment. Plenty of people will rise to the challenges, and if you intend being in that group, you need to address your attitude and motivation to what would be a very difficult, challenging, frustrating and expensive future.
