Computer-based test Logic Games how to do

lsat2016

any engineer/math majors who found it terribly difficult to do LG on computer-based test, and were able to get into 17x on computer-based lsat official administration?

how exactly do you work on lg on paper for every answer choice?

it seems much more difficult than LG during paper-based test days, as most if not almost all answer choices need transcribing on paper to be worked on.
earlier the answer choices were already on paper, so one could just draw on their top or check them against own diagram on paper.
i find it almost impossible now.

i have taken LSAT before during its paper-based days and have a 17x score, which is now expiring, and need retake.
LG was almost perfect for me on paper in 35 min.
but i have taken PT several times on computer now and it's much worse.
