Two official sources can make this look more confusing than it is.
The FAA Airman Knowledge Testing Matrix lists the Unmanned Aircraft General – Small (UAG) exam as 60 questions. PSI’s current UAG Applicant Information Bulletin gives the extra detail: the exam has 60 scored questions plus 5 unscored validation questions.
So the answer depends on what you are counting.
You are administered 65 questions. Only 60 determine your score.
The other five are unscored validation questions. They do not count for or against your result, and the full session still runs on the same 120-minute clock.
The FAA says 60. PSI says 60 + 5. Both can be right.
If you open the FAA’s current Airman Knowledge Testing Matrix, the UAG row shows:
- 60 questions
- 2.0 hours
- 70% passing score
That is the scored exam.
PSI’s Unmanned Aircraft General – Small Applicant Information Bulletin, effective September 29, 2025, is more specific. It lists:
- 60 scored questions
- 5 unscored validation questions
- 120 minutes
- 70% correct to pass
PSI then says that the five validation questions are administered in addition to the 60 scored questions and that the 120-minute test time already includes time to answer them.
That is why one Part 107 study site may say “60 questions” while another says “65.” One is counting the questions that determine your score. The other is counting everything you will see during the session.
What are Part 107 validation questions?
The five extra questions are not a bonus section and they are not tie-breakers.
They are developmental questions used in the FAA’s test-development process. PSI explains that the FAA uses them to evaluate the statistical performance of new questions before deciding whether those questions should later be included in scored sets.
You are not told which five questions are unscored while you are taking the exam.
That means the only sensible strategy is to treat all 65 questions as real questions and answer each one normally.
Does the Part 107 test still give you two hours?
Yes.
The current UAG specification allows 120 minutes for the full testing session, including the five validation questions.
For 65 administered questions, that works out to about 1 minute 51 seconds per question on average. Some regulation questions will take far less than that. A sectional-chart or calculation question may take longer.
The useful lesson is not “rush.” It is “practice under the format you will actually see.”
What percentage of the Part 107 test is each subject?
The current PSI blueprint divides the 60 scored questions across five content areas:
| Content area | PSI allocation | Approx. questions out of 60* |
|---|---|---|
| Regulations | 48% | 29 |
| Airspace Classification and Operating Requirements | 20% | 12 |
| Weather | 5% | 3 |
| Loading and Performance | 2% | 1 |
| Operations | 25% | 15 |
*The question counts are a practical rounding of the published percentages for study planning. The percentages are official; the rounded counts should not be treated as a promise about the exact composition of an individual test form.
The FAA announced in its August 2025 Airman Testing Community Advisory that the old UAG weighting table in the Remote Pilot ACS had become obsolete and directed applicants to the PSI bulletin for the updated blueprint. The new allocation took effect September 29, 2025.
Regulations is 48%. That does not mean 48% of the test is sitting inside Part 107.
This is where the blueprint is easy to misread.
“Regulations — 48%” is a test-content category. It is not a statement that 48% of every answer can be found simply by reading 14 CFR Part 107 from top to bottom.
I learned that while source-tagging my own Part 107 practice bank. Questions that feel like “Part 107 questions” often trace to another FAA source: the Aeronautical Information Manual, the Aeronautical Chart User’s Guide, the Remote Pilot Study Guide, an Advisory Circular, Part 48, Part 89, or another source.
That is the reason Office20’s study material names the FAA source behind each answer rather than asking you to trust an answer key.
If you want the longer explanation, read Do You Have to Read All of Part 107 to Pass the Knowledge Test?
Did the FAA change the subjects on the UAG exam?
No. The weighting changed; the underlying subjects did not.
In the August 2025 advisory, the FAA said the UAG test topics and subject matter did not change as a result of the assessment. The questions were reviewed for alignment with the ACS and FAA reference material, and the blueprint was updated.
That distinction matters when you use an older study guide. An explanation of Class D airspace or weather may still be perfectly useful even if the guide’s old percentage table is no longer current.
What should you study first?
The new weighting gives you a rational way to allocate time:
- Regulations and Operations deserve the largest share of your study time.
- Airspace deserves serious practice, not just memorization. It is 20% of the scored blueprint.
- Weather and Loading & Performance are smaller categories, not optional categories. A question still affects your score if it is one of the scored questions you receive.
Airspace deserves extra attention in 2026 for another reason. Beginning October 26, 2026, the FAA says UAG image-based questions may use current chart images that are not found in the printed testing supplement. The date was corrected from October 27 in the FAA’s August 2026 advisory.
That makes procedure more valuable than picture memory. Office20’s sectional-chart guide walks through the lookup in order using real chart values.
Why does Office20 use a 60-question scored mock exam?
Because the 60 questions are the questions that determine your FAA score.
The current Office20 mock exam is designed around that scored portion and the current PSI content-area blueprint. That makes it a scored-question simulation.
There is a separate issue: test-day pacing. The real PSI session currently administers five additional unscored validation questions within those same 120 minutes.
Office20 is therefore separating two ideas that are often blurred together:
- Score simulation: 60 scored questions using the current blueprint.
- Test-day simulation: 65 administered questions, with five simulated unscored questions hidden among the 60 scored questions, all within 120 minutes.
The second format is being added to the Office20 test suite so practice can match the pacing and uncertainty of the actual session more closely.
Practice questions on this

A. 60, all scored
B. 65, with 60 scored and 5 unscored validation questions
C. 65, all scored

Answer: B. PSI lists 60 scored questions plus five unscored validation questions. The five do not count for or against your score.
2. What is the purpose of the five validation questions?
A. To replace scored questions answered incorrectly
B. To evaluate new questions before they may enter scored sets
C. To determine whether an applicant receives an endorsement
Show answer
Answer: B. PSI says the validation questions allow the FAA to evaluate the statistical performance of new questions as part of the exam-development process.
3. Which content area currently has the largest allocation on the scored UAG blueprint?
A. Airspace Classification and Operating Requirements
B. Regulations
C. Operations
Show answer
Answer: B. The current PSI blueprint allocates 48% to Regulations, 25% to Operations, and 20% to Airspace.
The short version
- The FAA testing matrix lists 60 questions for UAG.
- PSI gives the fuller test-day format: 60 scored + 5 unscored validation questions.
- You therefore see 65 questions, but only 60 determine your score.
- The five validation questions do not count for or against you.
- You still get 120 minutes total.
- The passing score is 70% on the scored questions.
- The current scored blueprint is Regulations 48%, Airspace 20%, Weather 5%, Loading & Performance 2%, Operations 25%.
- The current blueprint took effect September 29, 2025.
- For UAG chart questions, the FAA’s current date for the new current-chart-image change is October 26, 2026, corrected from October 27.
