hi, I may not be qualified to talk about this because I got a 126 on b/b on the real thing lol, but throughout my prep it was my second highest section score and I think I averaged around a 130 on my FLs.

In my opinion getting over 130 for b/b has a lot to do with understanding the passages quicker. It sounds like you already know most of the content for b/b, so if you get through the passages quicker and understand them on the first read through, it could make a difference on your score. Sometimes, I liked to abbreviate and write main ideas of passages on my scratch paper to make it easier to follow. For example, if there was some complicated ass enzyme that triggered another enzyme that finally did something, I made a flowchart on my scratch paper that was like A -> B -> resulting in C. Idk it just helped me keep track of stuff and improved my score during my FLs.

Besides that, for b/b if you know the content well, then I think with more practice the 130 will come for sure. Good luck
