Do all Law Schools use the index formula that computes your UGPA? adding withdrawals and f's into your gpa? I am mainly interested in which schools in New York follow that. Thank you

I have been studying for the LSAT and I was doing great on the logic games however I am still practicing and have not taken timed exams of the entire PT. I would like to know your opinions on repeating PTs not necessarily limited to logic games but rather the other sections as well.
