I encourage you to keep at it and to consider it a worthwhile challenge. It's like looking for gold; you don't find it it under every stone. 😉
I have colleagues whose first language is not English, so I suggest an approach.that often works for them.
Firstly,drill yourself on as many practice questions as you can find, and try for accuracy first time through.
Then, try try for speed and accuracy on subsequent drills. Keep drilling until you are as comfortable as possible. I do not suggest rote memorization; rather, I do suggest complete understanding of the CBK matter.
Secondly, to make sure you have understanding of the matter, go through tables of contents and test yourself (or, better still, have others quiz you.) Make questions and study from them. Accuracy first; speed and accuracy second.
Read as much as you can on the 8 domains, and make notes on what you read. Make your own questions from your readings. Have others make questions, too.
To succeed, you must completely understand the terms and concepts. Many questions seem to hinge on comparsions and distracters, and this is meant to test your fundamental understanding of the matter.
When I see a question I look to see the most obvious howlers (the most untrue point there is) and immediately ignore it. Then I look for what I call "the truthiest" answer. If I am completely bewildered by the question, then I try to give the best guess.
As English is not your first language, I believe the test is provided in other languages. If you are fluent in another language in which the exam is offered, prepare for that.
Another suggestion is to form a study group with as many colleagues as you can. Try to include people whose mother tongue is English and ask them why they think one answer is better than another
Make a plan to succeed. Part of what makes a professional in any field is "finding a way." It takes time, and it's worth it.
Best wishes for success.
