We just used a book to study from. The HSPT was not that hard compared to the SSAT. DC was able to get a 99% on the HSPT but only 85% on SSAT. We did tutoring for the SSAT and it helped with the HSPT. Honestly, the catholic schools prepare you for the HSPT. My DC practiced a lot of the grammar in her English class and the math is not that hard, I’m not even sure algebra was on it. The reading comprehension is comparable to any standardized test.
