I didnt have any research questions, but when i took it (Q1 2017) it had not changed formats yet. I had just the MCQ modules and the WC.
My goal was to leave 1 hour for the WC and spread the rest of my time out over the MCQ. I remember feeling very comfortable with the materials going in and walked out thinking I had been kicked in the nuts by IT questions. A ton of those must have been pre-test questions since I fared alright on the exam score wise. I think I finished with about 20 mins left.
For the WCs, the guidance I had been given (by Roger and by my coworkers who had taken BEC already) was to just above all things keep to the format:
Paragraph 1 – tell them what you are going to tell them
Paragraph 2 – tell them
Paragraph 3 – tell them what you told them.
Seems simple I know, but it works. Make sure you have a proper introduction or salutation as the problem presents itself, and in P1 restate their question/request and explain that you are going to assist blah blah blah. Paragraph 2 get to the guts of your position…fake it if you dont know what the subject matter is. Be sure to restate questions and use the key words or concepts from the question. Use proper grammar and punctuation and spelling. Don't ramble and NO BULLET POINTS or LISTS.
Paragraph three “in conclusion”, blah blah blah recap paragraph 2. End with a proper signoff/closing (thank you for reaching out, please contact me if you have any further questions).
For my two WCs I knew the subject matter solid of one and only half knew the second. i stuck to the above and ended up getting stronger scores on my WC.
Also, I drafted my two WC responses somewhat simultaneously and found it actually worked well for me. I started on the one and jammed the first paragraph or so, then switched to number two and drafted paragraph 1 and 2, then flipped back to 1 and kept doing that. I found it helped me clear my head from one to the next and I came back to the WC each time with a somewhat fresher perspective. It also forced me to stick to my structure more.
Good luck to you, kick its ass
