Usually As.

90+ in the HSPT categories for that subject. I’ve also heard that schools require strong grades in that subject, but not sure if that means all As or As and Bs, if paired with a 90 score on the HSPT.

90 in that section.

For Bio, you need good math scores.
There is a world language placement exam that is different than HSPT.

The pre-reqs for classes should be in the school’s course catalog. Generally it is 90 or above in addition to a placement test for math, world language, etc.

I know Math placement at many of the Catholic high schools is determined by a separate test that the schools administer after admissions is complete. I understand that placement in other Honors courses Freshman year is largely determined by HSPT scores. What kind of HSPT scores are needed in sub-tests for placement in other honors courses Freshman year? I’m not sure what to expect!
