There's much to be said about getting comfortable with taking post-education exams in general. The whole thing feels unfamiliar and awkward until do have a number of them under your belt. This anxiety is actually quite common from your description if not outright normal.
I want you to keep one thing in mind here. The more certification exams you take the easier they become over time. Frankly, I've sat for so many at this point in my career I tend to be more bored than anxious. Which is difficult to imagine but true.
It's not the format but the experience and applied knowledge that makes the exam difficult not the format.

It's not about it being easy or hard. The fact is that this test has now become a reading comprehension test. I rather them make me understand the concept as opposed to deciphering what the heck they are asking. Broken English is just not the right approach.
