How to pass the PTCB exam the first time
Take a full 90-question mock first to find your weakest domain. Learn the top 200 drugs in class groups, make one card for every federal number, practise calculations with the units written out, and book the PTCE only when two different mocks clear 80%.

How long does it take to study for the PTCB?
About four weeks of an hour a day for most people who have finished a program or work in a pharmacy; longer if you are new to pharmacy or if your first mock is under 60%.
| Week | What to do |
|---|---|
| Week 1 | Take a full 90-question mock on the clock. Learn 50 drugs by class (cardiovascular first) and the 14 most common stems. One medications drill. |
| Week 2 | Federal Requirements: schedules with examples, refills, partial fills, transfers, DEA forms, inventories, CMEA, DSCSA. Two law drills. 50 more drugs. |
| Week 3 | Patient safety: error-prone abbreviations, tall man pairs, high-alert drugs, error types and reporting. Pharmacy math every day for 20 minutes. 50 more drugs. |
| Week 4 | The last 50 drugs. Redo every miss so far. A second full mock on new questions; book the PTCE if it clears 80%, otherwise drill the weakest domain and take a third. |
What is the best way to memorize drugs for the PTCB?
In class groups, with the stem first: one card per drug with generic, brand, class, main use and one side effect, studied a group at a time and reviewed on a spaced schedule.
- Start with the classes that carry the most drugs: cardiovascular, diabetes, mental health, pain and antibiotics.
- Learn the stem before the drugs: -pril, -sartan, -olol, -statin, -prazole, -azepam, -floxacin.
- Say the generic out loud when you see the brand, and the brand when you see the generic.
- Add one side effect per class and one interaction you would flag.
- Review yesterday's cards before learning new ones, and every card again at the end of the week.
The PTCB medications practice test has a free drill drawn from a table of more than 130 high-volume drugs, so it tests whether the cards have stuck on combinations you have not seen.
What federal rules should I memorize for the PTCB?
One card of numbers decides most law questions: refills by schedule, the 72-hour and 30-day partial fill windows, the 7-day emergency C-II rule, one transfer for III to V, DEA forms 222, 106, 41 and 224, the 2-year inventory and records, and the CMEA limits.
| Rule | Federal requirement | Source |
|---|---|---|
| Schedule II refills | None; a new prescription each time | 21 CFR 1306.12 |
| Schedule III and IV refills | Up to 5, within 6 months of the date written | 21 CFR 1306.22 |
| Schedule V refills | As the prescriber authorizes | 21 CFR 1306.22 |
| C-II partial fill, pharmacy short | Balance within 72 hours, or notify the prescriber | 21 CFR 1306.13(a) |
| C-II partial fill, patient or prescriber asks | Balance within 30 days of the date written | 21 CFR 1306.13(b) |
| Emergency oral C-II order | Written prescription to the pharmacy within 7 days | 21 CFR 1306.11(d) |
| C-III to V transfer | Once only, unless the pharmacies share a real-time online database | 21 CFR 1306.25 |
| Ordering Schedule I and II | DEA Form 222, or CSOS electronically | 21 CFR part 1305 |
| Theft or significant loss | DEA Form 106; written notice within 1 business day of discovery | 21 CFR 1301.76(b) |
| Destruction | DEA Form 41 | 21 CFR 1317 |
| Inventory | Initial, then every 2 years; exact count for C-II | 21 CFR 1304.11 |
| Records | Kept at least 2 years | 21 CFR 1304.04 |
Then learn which drugs sit in which schedule, with two or three examples each; a refill question is useless if you do not know the drug is C-IV. The free pharmacy law drill checks both.

How do I get better at pharmacy math?
Twenty minutes a day, with the units written on every number. Most errors are setup errors, not arithmetic: a missed conversion, a daily dose used as a single dose, or an answer in the wrong unit.
- Convert first: pounds to kilograms (÷ 2.2), teaspoons to mL (× 5), grams to milligrams (× 1,000).
- Read whether a dose is per day or per dose, and divide by the doses per day if needed.
- For concentrations, write dose ÷ strength × volume, and cancel the units.
- For rates, read whether the answer is mL per hour or drops per minute.
- Check every answer for sense before you choose.
PTCB-style question 1 · Weight-based doses
A child weighs 44 lb. Amoxicillin is ordered at 40 mg/kg/day, divided every 12 hours. The suspension is 400 mg/5 mL. How many mL is each dose?
- A5 mL
- B10 mL
- C2.5 mL
- D11 mL
Worked answer
A: 5 mL. 44 lb ÷ 2.2 = 20 kg. 40 mg × 20 kg = 800 mg a day, given as two doses of 400 mg. At 400 mg per 5 mL, each dose is 5 mL.
- 44 lb ÷ 2.2 = 20 kg
- 40 mg/kg/day × 20 kg = 800 mg/day; ÷ 2 doses = 400 mg
- 400 mg ÷ 400 mg × 5 mL = 5 mL
The trap: Using pounds as kilograms: 40 × 44 = 1,760 mg a day gives 11 mL a dose, more than double the right amount.
PTCB-style question 2 · Error prevention
A technician pulls clonazepam for a prescription written for clonidine. Which step in the filling process is designed to catch this before the pharmacist check?
- AScanning the stock bottle bar code against the prescription
- BCounting the tablets twice
- CChecking the stock bottle's expiration date
- DConfirming the patient's date of birth at pickup
Show the worked answer
A: Scanning the stock bottle bar code against the prescription. Scanning the stock bottle matches its NDC to the drug on the prescription, so a look-alike name pulled by mistake is flagged at once. Counting, expiration checks and patient identifiers do not compare the drug itself.
- The error is the wrong drug, a look-alike name.
- Only one step compares the drug in hand with the drug ordered: the bar code scan.
- The pharmacist's final check is a second barrier, not the first.
The trap: Choosing the date-of-birth check. It confirms the right patient, not the right drug.
The pharmacy math practice test has a free drill with every calculation worked step by step, and new numbers in every set.
How should I use PTCB practice tests?
As a map, not a score: every miss points to a fact or rule, so write it down, drill that domain, and only then take another full mock on new questions.
Take the first full mock before you study much. It tells you whether you need two weeks or six, and which domain to start with. The free PTCB practice test scores each domain separately.
Do not retake the same questions to see a better number; use new ones. A rising score on questions you have seen proves memory, not readiness. What 80% means against PTCB's scaled 1400 line is explained on PTCB passing score.
What should I do on PTCB exam day?
Bring valid photo ID that matches your PTCB account, arrive early or set up your online room ahead of time, use the on-screen calculator for every calculation, and answer every question.
- For an online proctored exam, run the system check the day before and clear your desk and walls.
- You have 1 hour 50 minutes for 90 questions, about 73 seconds each. Flag anything slow and come back to it.
- Read every drug name twice: look-alike names are the exam's favorite distractor.
- Read law questions for the word "federal" and the schedule of the drug.
- Answer every question; there is no penalty for a wrong answer, and 10 unscored questions are hidden among them.
If you also plan a career in clinical care, our CCMA practice test and CNA practice test follow the same method, and the PTCB exam guide covers eligibility, fees and renewal.
