@mick I am what one might call a non-traditional CPA candidate. I have been working in IT for 25+ years now so my experience with all of the CPA exam sections are purely theoretical. My undergrad back in early 90s was in accounting so I did have a conceptual base. I write this only to give you comfort that even with no current experience one can tackle this exam.
I personally do not rely too much on MCQs. I think the reading of text on GLEIM or some other source like short videos on specific topics to get some level of conceptual clarity is important. Once you have that one can do the MCQs more as a revision. Drilling MCQs in isolation does not work for me.
On BEC specifically:
GLEIM does a very good job of preparing you for the exam. I felt I had very good grasp of economics and costing related areas.
I struggled with COSO , COBIT and even after reading the text a couple of times. I took a calculated risk in not worrying too much about these ‘minor' topics.
Also BEC was my very first subject. Some of the GLEIM material on economics concepts was not very well written in my opinion. For those, I went on youtube and khanacademy to understand those topics better. Just for a change of scenery learn some of those economic concepts from a Econ-101 course freely available online.
I feel the Written Communications section is literally free points. Just follow a decent structure, some key words indicating you are aware of the concept tested in the question.
Just follow the GLEIM methodology and take the practice exam. If you score over 70 on that, there is a very high probability , you will do ok in the actual exam.
Relax , you have made it this far, you will be fine.
@monikernc‘s advice is sound. The process and consistency does help in the end. I am not even close to his level of discipline in terms of study method, so I should consider myself fortunate to have made it this far.
I am on the last section REG and I hope to finish this journey soon. Can't wait.
Good luck
