Summary of HESI Problems 🔥

- The anatomy and physiology portion of the app is not helpful for the HESI, as the questions are not formed like they are on the real test and the information is much more specific than what is on the app.

- The bio and chem sections of the app are not an indication of what would be on the HESI, as one user missed the bio section by 3 points despite consistently scoring in the 90s on the app.
