October 1993 LSAT #12 and 13

Can someone please explain how to solve 12 and 13? Also, please provide me with some tips to solve these questions quicker. It's real time consuming and if I see similar questions on actual test, I'll panic and miss all the questions! Thanks in advance.

Y: N L J/ K _
N: p j/k _

With m and q being the only two possibilities for the empty slots.
We know that if q is in then k is in, so if q is in the game is fully determined. If m is in, either j or k could be in, so there are three possibilities, q, mk, and mj.
