Readings or the MCAT

Hey guys! I'm kind of new to posting on studentdoctor but I was hoping to gain some insight. I was wondering what journals/ books you guys have found to help with speed/ efficiency of reading. I am using Kaplan and have seen significant improvements in my scores over the past few weeks, however, if I find that the real MCAT has longer passages, I will be in trouble because I just finish on time.

Thanks guys!
