The ALEKS math test counts for chemistry too, so you don’t need to do any extra studying for chem topics if I recall correctly. They want to make sure you can do the math involved in courses like Chem 110.

With a 61+ on ALEKS, you can take Chem 110 if you had chemistry in HS. And you want to place into Chem 110, since it’s in your Recommended Academic Plan: https://rap.psu.edu/recommended-academic-plan-toxicology-tox-commonwealth-campuses-and-university-park
Edit: Also, you have the opportunity to complete learning modules and retake the assessment for a better score, so don’t stress too much.
