I took BEC exam on July 14, and passed the exam with 79.
The first two sessions were moderate in difficulty, but the third one was challenging. I spent so much time on the third session, so that I did not have enough time left for writing.
I were not familiar with all three topics, but just tried to write anything I know that seems like related to the topics. I wrote the first and last paragraph, and wrote one or two sentences for paragraphs in the middle for all three topics, and then budgeted my time to fill in more content for each topic. For one topic, I wrote a lot and it was developed very well. For other two topics, they were short, but with complete structures.
I really was not sure about my exam, but good to know I passed it!
