Wow...a 13...thats amazing score. For how long did you read the economist before taking the real exam? Im frustrated with the verbal. Im ESL which adds another level of difficulty.
I read the Economist for about two months before I took the exam and also had to make time for studying BS and PS too.
I'm a native English speaker, as are both my parents, and I've always been an avid reader. Therefore, studying for VR could easily take longer and require more of a time commitment for students who are not native English speakers or do not read for fun. (Maybe someone in one of those categories could chime in here?)
Some people on SDN have recommended reading popular fiction like "The Hunger Games" or "Harry Potter" to sharpen your reading skills and speed. Again, my issue is that the level of difficulty and the interest level of popular fiction is not at all representative of VR passages.
Possibly - and this is an untested hypothesis - it might be better to read "The Lord of the Rings", "Alice in Wonderland", "Dracula", which are wordier and more complex, but are engaging and relatively easy to read compared to most classics.
The reason that I read the Economist is because I know very little about its subject matter. If you're someone who's very well versed in international politics or who tracks the stock market for a hobby, it probably wouldn't be as difficult for you. I know some people are more intimidated by the arts passages, in which case something like the New Yorker could suffice.
In any case, it worked for me to zero in on a subject I am not comfortable with. If you find it boring and don't understand the terminology, you'll get easily confused and lose interest. I guess that forcing yourself to read it increases the discipline and focus necessary for the awful passages on the VR. Forcing yourself to try and understand it (summarize the article at the end or throughout) also helps you learn to extract meaning from these dense passages.
Another note - especially on TBR BS, I would sometimes not even read the passage unless the question referred to it. If it was purely a fact based question, I would simply answer it out of knowledge and not waste time reading; pick out the obvious correct answer and move on. The same strategies that I used on the science sections caused me to trip up on the verbal, where you do have to thoroughly read and get some understanding from the passage, and where it is important to read and consider every answer choice.
Also, the real MCAT had much of that infamous "experimental biology" rather than fact based or conceptual questions and so being able to analyze the passage, questions and answers - many of which are not very straightforward - matters on BS not only VR.
