#guessing tips

I definitely agree! Because the questions on the ACT are right next to the part they are referring to in the passage, it's really easy to answer questions just as you go along. 

Hmmm, for CR, I personally read the questions first and then annotated the passage for questions as I went along; you could possibly try that. 

Ooh for guessing tips, I often just guess the answer that looks most like everything else. Here, let me try to give you a math example (it applied to CR as well though) If your answers are: a) -3/2 b) 3/2 c) 3/4 d) -3/5 e) 5/2 and you have no idea, I would choose b. Why b? Because it looks most like every other answer. The majority of the five answers are positive, have a numerator of 3, and a denominator of 2. 

Also, remember that problems get harder as you go along. So, if you're on the last problem of a section, the most obvious answer probably isn't the right one. Also the answer, "It cannot be determined from the information given" is more likely to be correct at the beginning of the section-at the end of the section, it is probably incorrect.
