This book was written for the ACT English section. Why the English section? Because it's the first section the ACT and along with the math, the most "coachable" section. Students can improve their score 4 to 8 points or more on this section by preparation. The result you get will depend on what your score is currently and how much study and practice you put in. Students close to or above 30 will not get as great an improvement. One reason is that they are so near the maximum score of 36. Students in the middle or lower range can expect large improvements.
