Based on my roller coaster ride experience of trying to prepare for the LSAT... I'm not drilling or PTing until I at least get through foundations first! Then maybe just maybe I might start drilling once I get pass the "Must Be True" section in LR. I'm overly committed to first establishing a solid foundation before entering the PT realm and this is based on my previous unsuccessful LSAT preparation attempts of trying PT myself into my target score... That approach simply didn't work for me. Good luck!
