BR breakthrough

I've been stuck at 161 for three separate tests now and its been VERY frustrating but I finally got my BR to hit my goal score!! Went from -3 to 0, -6 to -3, -8 to -1, and then -4 to -2. I keep running into an issue where I do so well on the first few RC passages (-0, -2, -0) and then I don't bank enough time to get through the last passage and have to rush through it in 4 minutes. That's really the main section I need to close the gap on I've noticed, because my LR scores have continuously improved even with time, so I guess it's time to just speed drill RC until september 😭. Doable within a month?? I feel like it could be because I've identified the main issue there
