I really enjoy working with 7th and 8th graders who want to take the SHSAT test for the specialize high schools in New York City. They have a desire to work and get high scores required for admission.
With time and patience, two things the average 13 year old has in short supply, the verbal part of the test can be mastered. I have used all the test prep books and am now developing my own questions for this summer. Old tests are hard to find and the books only give two or three exams to use with the kids.
