Seven days is enough if you spend them on the right five topics. Most people spend them re-reading a textbook and remembering nothing under pressure.
Take one full-length practice set with no study at all. Do not look anything up. The score does not matter; the distribution of your misses does. Sort every wrong answer into: time and temperature, cross-contamination, personal hygiene, cleaning and sanitizing, or facility and pest management.
You will almost always find that two buckets produced about 80 percent of your misses. Ignore everything else for now. If time and temperature is one of them, start with the cooling and reheating rules, because they carry the most questions and the most confusion.
The exam tests the when, not the how. Learn the list of handwashing triggers as a list, and learn that a single-use glove never substitutes for handwashing.
This is the cheapest bucket to fix. Sanitizer concentration, contact time, and the three-compartment sink order: wash, rinse, sanitize, air dry. Never towel dry.
A fresh set, not the one from day 1. Re-taking the same set measures memory of the answer key, not understanding. Compare the bucket distribution against your diagnostic. You are looking for the number of buckets above one third of your misses to fall to zero.
Approved suppliers, receiving temperatures, corrective actions, and integrated pest management. Then one final targeted drill on whichever bucket is still weakest.
Do not cram on the last day. Take a short set in the morning, review only your two weakest buckets for one hour, and stop. Fatigue is what turns a passing score into a failing one.
