If i wanted to take the 9th grade shsat for new york specialized high school. Will they provide me a practice book?

No, the New York City Department of Education (NYCDOE) does not provide a specific practice book for the Specialized High Schools Admissions Test (SHSAT). They do, however, provide sample questions and released tests on their website. These resources are your best bet for official practice materials. You'll need to find practice books from other publishers if you want more extensive practice materials.
