<p>They are excruciatingly hard for me.. I really don't want to do them, but do many problems concerning the topic show up on the real SAT test?</p>
<p>That type of problem is worth mastering.</p>
<p>The way that Gruber’s presents with the annoying charts, or another way?</p>
<p>What’s the other way?</p>
<p>I am currently working through that part of the book as well and I was tempted to skip them because they were very confusing. After I carefully read through the example problems again and started a few of them I started to get the hang of it. The chart method seems annoying but it really helps to keep all the info organized and helps me see certain realationships. First I read a problem and then tried to set up the chart on my own, if I set it up wrong, I fixed it and then read the answer explanations. Doing that for the first few problems really helped me understand the concept better. Now I try to solve a problem on my own (or until i get stuck), before I look at the answers.</p>
