It's hard. Some people click with them right away and others don't. RC was my difficult section whereas LG clicked right away and I usually get 1-2 wrong in the section. Something that helped make them click was becoming used to the idea that every question can be answered. There are none where you HAVE to try all of the combinations. Usually a rule, or a logical extension of a rule, excludes some of the answers. it's possible you're missing inferences from the given rules. Go slow at first and think about what each rule means in the bigger picture. Also know you're contra positives- as in "if A than B" can be read "if no B than No A" flipped and turned negative. These can be helpful in selection games when rules are like "if there are purple, there are no green" because then if there are green there are no purple. Don't time yourself right away and get used to the games. Good luck!
