Study plan extra practice

Hi everyone! Seeking some advice.

I have the study plan that 7Sage generated for me and I am still doing the foundations/core curriculum. Should I also start adding in my own drills? Or wait until I reach the practice phase? For reference I took the January LSAT so I already have a good bit of practice under my belt, but I want to strength my foundations before the April test. Looking to improve 6-10 points.
