Valued PPI C.
Helped me pass the exam - highly recommend
I passed the Chemical PE exam in June 2020. My only study resources were PPI learning hub and the NCEES practice exam. PPI questions contained a surprising number of errors, but the administrators were very responsive when I submitted reports of content errors. Some of the errors were likely related to transition of the practice questions from paper to CBT type exam (the only reference allowed in the CBT exam is the NCEES manual, so practice questions must take this into consideration). It was evident to me that PPI is striving to continuously improve the platform. It’s also worth noting that the PPI learning hub is by far the most affordable method of preparation compared to other sites.
