About this test
PTCB Practice Test 4 draws from set 4, so it is fresh even if you have worked through the first three. Because Medications is 35% of the exam, seven of these 20 questions come from that domain, and it is usually where recall gaps first become obvious.
If the medication questions here feel shaky, pair this test with the drug class identification quiz, the brand and generic quiz, and the drug-class study guides before continuing the series.

Key concepts to know
Medications is where scores move
More than a third of the exam is Medications, so improving brand-generic recall and class identification has the largest payoff. Treat every medication miss here as a high-value fix.
Read the cited explanation on drug questions
Drug questions often hinge on one detail: a salt form, a suffix, a single interaction. The explanations are where those distinctions live, so read them even on questions you answered correctly.
Practice Test 4: FAQ
Why are there so many medication questions?
Medications is the largest PTCE domain at 35% of the exam, so a weighted mini test naturally includes the most questions from it. Test 4 keeps that same proportion.
Where should I study if I miss the drug questions?
Start with the drug class identification and brand and generic quizzes, then read the drug-class study guides. Those target exactly what medication questions test.
