Self-directed Texas Master exam-preparation practice: work through original questions, compare the calculation steps and build your own code-book review routine.
The Calculations part is where Texas Master candidates get stuck
Prepare Knowledge and Calculations as separate study tasks. Use the 368-question bank, timed two-part mocks and worked calculation solutions to identify the first step to revisit, then return for another practice attempt.
Built for the Texas Master exam and nothing else
- The PSI two-part format. Part 1, NEC Knowledge: 75 questions in 150 minutes. Part 2, Calculations: 33 questions in 170 minutes. You need 70% on each part (49 of the 70 scored questions in NEC Knowledge, 21 of the 30 in Calculations), and time left in one part does not carry over to the next.
- Weighted like the real exam. Every mock follows the scored items per topic area in the Texas PSI content outline. In Calculations, services and service equipment carry 8 of the 30 scored points and motors and generators carry 6, so the mocks give them the same weight.
- The 2026 NEC. Texas exams follow the 2026 NEC from September 1, 2026. Load calculations moved from Article 220 to the new Article 120, and the questions and lookup paths use the 2026 locations.
- Step-by-step calculations. Services, feeders, motors, transformers, conductors, raceway fill, EV chargers, RV parks and marinas: every calculation question shows the rule, the numbers given, every step, the rounding where it matters, and why each wrong option is wrong.
What you get
- 10 full two-part timed mocks (Mock A–J). Each form has 75 NEC Knowledge questions and 33 Calculations questions. The ten forms draw from the 368-question bank, so repeated attempts let you revisit the same topics in different timed forms.
- A score card after every mock. Your score for each part against the 70% pass line, your score for each official topic area, and one line that names any part that scored below 70% on this mock.
- Step-by-step solutions for all 110 calculation questions.
- 368 practice questions across all 20 PSI topic areas, by topic or as a full mock, with the answer after each one.
- Code-book navigation data for 321 questions. Use these locators as starting points for your own open-book review. For other questions, work from the explanation and your own 2026 NEC. Read Informational Notes as context and confirm the applicable section or table.
- Find-these-first list. The 60 code-book locations referenced most often by questions in this pack, ranked by frequency (Article 250, Article 430 and Article 120 first). PSI allows only permanent index tabs made or supplied by the NEC publisher; homemade tabs are not allowed in the exam room.
- Unlimited retakes of practice rounds and mocks, a wrong-answer list and a weak-area check.

Build a focused review routine
- Start with original practice questions for the Texas Master two-part format and work through the calculation explanations.
- Keep your 2026 NEC beside you. Use the available references and lookup aids to find the applicable rule, then compare it with your own reasoning.
- Use the dated practice-page corrections log when revisiting a question.
- Spot an error? Report it right from the question.
What makes a useful Master calculation error log?
A useful log names the wrong decision, not just the wrong answer. Use columns for the topic, reference, first incorrect step and the check you will apply next time. The Texas Master practice pack provides worked calculation solutions that you can compare with your own work.

How can I judge which Master topics need more practice?
Use your own attempts to identify weak topics rather than treating another person's difficulty rating as a study plan. Try a mock, group the misses by topic and inspect the explanations. The Texas Master pack describes topic results and worked calculations for that review.

FAQ
What if the arithmetic was right?
Check whether you selected the intended rule and used the correct given values.
Does the pack include worked explanations?
Its product page describes step-by-step calculation solutions and explanations of incorrect choices.
Does a difficult practice question mean I am not ready?
One question is a reason to inspect a topic. Make your plan from several attempts and your ability to explain the work.
Should I ignore topics I answered correctly?
Review any answer you guessed, even when it was marked correct.
Find your weak topics, then rehearse both Master exam portions
This addition to the US$79 Texas Master practice pack includes a 40-question diagnostic PDF, an automatically scored diagnostic spreadsheet, two timed practice sets with separate answer booklets, and a one-page outline map. The price stays US$79.
- Complete the diagnostic and enter your answers in the spreadsheet.
- Use the topic scores and weak-topic ranks to choose the matching review blocks in the diagnostic PDF.
- Work through those blocks and the existing practice pack with your 2026 NEC.
- Keep the two mocks unseen until you are ready for a timed rehearsal.
Each mock contains 70 scored NEC Knowledge questions for 150 minutes and 30 scored Calculations questions for 170 minutes. Score the portions separately: 49/70 and 21/30 correspond to 70%. Unused time does not transfer between portions. The actual PSI exam has 75 Knowledge items including 5 unscored, and 33 Calculations items including 3 unscored. The mocks contain the scored items only.

Try an actual studio station: PV, storage and backup: trace every source
Learn the method
Read a multi-source drawing as an energy-boundary problem: utility, PV, battery and generator sources may have different behavior and stored-energy conditions. A status label or one open symbol does not prove isolation of every source. For the supplied energy-only model, usable AC energy=nominal battery energy (kWh)×usable fraction×conversion efficiency; duration=usable AC energy (kWh)/load (kW) only if the assumed continuous power can actually be delivered. Real interconnection, transfer, protection, emergency classification and isolation require approved design and qualified procedures.
Fictional packet
Fictional drawing lists utility, PV, battery and generator connections, but the transfer/control revision is missing. Battery 10 kWh, usable fraction 0.80, conversion efficiency 0.90; hypothetical load 2 kW and inverter continuous rating 3 kW. The owner claims one open utility symbol makes the whole system safe.
Your attempt: Calculate the limited energy model and make a source/evidence register without an operating sequence.
Compare the worked guide
Usable modeled AC energy 7.2 kWh;2 kW is below the supplied 3 kW rating, giving idealized 3.6 h under all stated assumptions. List all four potential sources and the missing controlling drawing, actual operating states, ratings/loads and authorized safety/transfer review. The arithmetic and utility symbol prove neither actual backup performance nor isolation. Do not specify disconnecting or switching actions.
The included studio adds changed-condition retries, evidence notes and the related career bridge.
