Yup. Don't let that diagnostic get to you. You CAN still get into the 160's. I reached the 160's from a 13X diagnostic. The good thing going for you is that you have a 3.9x GPA and zero UG debt. Just work on the LSAT and you'll be good to go.
Don't touch a PT until you finish the curriculum... Then take 3-5 PTs, check your analytics and adjust fire from there. Doing them before you finish the curriculum is what we call "wasting PTs".
