How Many Questions Are on the PTCB Exam?

90 questions, 80 of them scored, in 110 minutes — about 73 seconds each. The four blueprint domains with their weights, the calculator rule, and when you can test.

The PTCB exam has 90 multiple-choice questions, of which 80 are scored and 10 are unscored. PTCB states it plainly: "The PTCE is a computer-based exam with 90 multiple-choice questions (80 scored questions and 10 unscored questions)." You answer all 90; only 80 of them count toward your result.

The ten questions that do not count

The ten extra items are pretest questions — questions PTCB is trialing before they count for anyone. Two details matter for how you sit the exam:

"Unscored questions are randomly placed throughout the exam and are not identified." You cannot spot them, so there is nothing to skip and no strategy to exploit: answer every question as though it counts, because you cannot know which ones do not.
Because the unscored items are spread through the whole exam, a question that feels off-topic or unusually hard is not necessarily a pretest item you can safely blow past.

How long you get

The exam itself runs 110 minutes — an hour and fifty minutes. PTCB describes the whole sitting as "Be prepared to commit 2 hours for the exam (5-minute tutorial, 1 hour and 50-minute exam, and 5-minute post-exam survey)." So the number to plan around is 110 minutes of exam time, inside roughly two hours at the test center seat — one clock for all 90 questions.

The arithmetic worth internalizing: 90 questions in 110 minutes is about 73 seconds per question on average. Any single item that runs past two minutes is borrowing time from three others.

What the exam covers

The PTCE blueprint is four domains, and the weight of each is published:

Domain	Blueprint weight
Medications	35%
Patient Safety and Quality Assurance	23.75%
Order Entry and Processing	22.50%
Federal Requirements	18.75%

One housekeeping note on the source: PTCB's pages disagree with each other here. The "At a Glance" article lists Order Entry and Processing at 22.25%, while the 2026 blueprint outline says 22.50%. The 22.25% figure appears to be a typo — the four weights must total 100%, and 35 + 23.75 + 22.25 + 18.75 = 99.75, while 35 + 23.75 + 22.50 + 18.75 = 100. The figure below uses 22.50%, the outline value.

Because only 80 questions are scored, a domain's weight can be turned into an estimate of how many scored questions it holds — the weight times 80:

Domain	Weight	Estimated scored questions (weight × 80)
Medications	35%	~28
Patient Safety and Quality Assurance	23.75%	~19
Order Entry and Processing	22.50%	~18
Federal Requirements	18.75%	~15

Treat those counts as an estimate, not a published number: the split of the 80 scored items across domains is derived here from the published percentages. It is a good guide to where the study weight belongs, not a promise about the form you will see.

How many math questions?

PTCB does not publish a count of calculation items, and there is no separate "math section." Calculations live inside the domains — most of them in Order Entry and Processing — so a calculation can appear anywhere in the exam, not in a block at the end. If you want to know how much math to expect, the honest answer is: enough that you should be comfortable with pharmacy calculations before you sit it, and no published count beyond that.

The calculator

You do not bring a calculator, but you are not doing arithmetic cold. "A calculator is built into the PTCB exam. A personal calculator may not be used under any circumstance." If you need a hand-held calculator, PTCB provides one on request if the test center has them available. The rule to remember: the on-screen calculator is the tool you will be using, so practice with one rather than your phone's.

When and where you take it

There are no fixed test dates. The PTCE runs year-round, and PTCB notes that "Most test centers offer exams Monday through Friday, with some Saturday options." You schedule yourself once your application is approved, and you have a 90-day authorization period to do it in — extendable twice at $20 each if you buy the extension before the period expires. The exam is offered "at more than 1,400 Pearson Test Centers nationwide, including more than 100 military bases," and it is taken in person: online testing is not available for the PTCE.

Knowing the shape of the exam is half the planning. The pass line of 1,400 and what makes the exam hard are the other half, and the full set of steps to get certified covers eligibility and cost.
